hi
I'm a vhdl developer and use frequently the quartus compile. This weekend is expired the evaluation licence for the Quartus II (my version is 15.0) and I've supplied the time-limited licence downloaded at the Altera licence page since I've an evaluation board for a Stratix 5.
After the first compilation I've noticed that the result is quite different from the evaluation full licence that the altera FAE has supplied me. So I've request a new evaluation full licence meanwhile the full licence will be provided by the supplier.
The problem is that despite I'm pointing the evaluation licence the quartus is still running as Time-limited.
Where is placed the setup to get back again the full Qurtus performance? It seems is still running as Tiime-limited since the .sof file is named as xxxtime-limited.sof.
Thanks in advance to anybody will solve this issue.

Hi,
I need to interface a image sensor (OnSemi Python300 - 4 LVDS lanes where each lane runs@360 MHz, 720 Mbps).
I'm confused between MAX10 and CYCLONE5 FPGAs for it.
Could anyone suggest me a dev kit for either of these FPGAs where I can directly connect the image sensor PCB? (I think it won't be good to connect it via just about any header pinas LVDS connections need to be matched in length and short. If I'm wrong, please correct me).
Thank you so much !
P.S. - If somebody could also help in choosing between these two FPGAs then that would be great too. I just need to take the image data, store it on a memory/RAM and later send it via some communication method like Ethernet/WiFi. The datarate from the sensor will be high (~700 mbps). Thanks again !

Hi,
If I am in the chip planner or in the RTL viewer and a select a block and then I can go and select Locate-> Resource Property Editor and then the Resource property editor opens.
My questions is: can I open Resource Property Editor in another way - i.e. without looking to locate someting?
What is the point of Resource Property Anyways? I failed to find this in altera documentation I only found this:
http://quartushelp.altera.com/14.0/m...rty_editor.htm
and it doesn't really say a lot to me.
Thank you in advance for your comments.

I am having difficulties getting the MTL Paint Demo to work under Quartus 15.0. When building the BSP, the ALT_ENHANCED_INTERRUPT_API_PRESENT flag is set. I make the appropriate modifications to the MTC_Init and mtc_ISR routines to handle the newer rather than the legacy interrupt interface and I can receive interrupts. I have a problem writing to the LCD, either through the gui_vpg or gui calls. If I choose the gui_vpg option and step through, the call to never returns. It ultimately calls vid_paint_block. It appears that this routine hangs after processing 128 lines when attempting the memcpy near the end of that routine.
Has anyone been able to run this demo in the Eclipse debugger in V15.0? Why would this happen here? It seems that the memory size should be enough.

I have a system, wherein user logic is interfaced to DDR1 SDRAM Controller using native interface in Cyclone 2 device. The project was built in Quartus 11.1 and when we generate the DDR1 IP, either Avalon-MM or Native interface could be generated.
Now, the whole idea is to change the memory module from DDR1 to DDR3 in Cyclone V device. But, when I try to generate the core, native interface is not supported and only Avalon interface is supported. Now I need some sort of code/IP which converts Avalon-MM to Native interface signals?
Can anybody help me regarding this?

Hi folks. I built a simple system using Qsys (packaged with Quartus Prime 15.1) with some onchip memory for cpu instruction and data, plus a separate dual port RAM (data width 32, 1024 bytes, base address 0x1000) for passing data back and forth between FPGA logic and CPU. The other components in the system are a uart, 50MHz clock and System ID component. Using a Terasic Cyclone V FPGA Starter Kit.
I initialize the RAM with a .hex file generated using the Quartus hex editor (word size 32, depth 256). For starters, just using the initialized memory and a simple application to read out the memory contents and printf to the uart. For some reason, only the last 124 addresses appear to provide the correct data and the rest is not instantly recognizable. Here's the code. Can anyone see why this is happening?
Code:
// dp_ram_test.c
#include <stdio.h>
#include <unistd.h>
#include "system.h"
int main()
{
int i=0;
unsigned dp_ram_addr = 0;
unsigned *dp_ram_ptr = 0;
printf("Begin...\n");
printf("Starting at address 0x0000%x\r\n", DP_RAM_BASE);
printf("Hex Addr (dec) : Contents\r\n");
printf("================= : ========\r\n");
for (i = 0; i < 1024; i++)
{
dp_ram_addr = DP_RAM_BASE + i;
dp_ram_ptr = (unsigned *)(dp_ram_addr);
printf("0x0000%x (%u) : %x %u\r\n", dp_ram_addr, dp_ram_addr, *dp_ram_ptr, *dp_ram_ptr);
}
return 0;
}
The hex file (as .pdf) and log file of uart output are attached. Any help would be great. Thanks in advance.

Hi,
I have got a question about the TK support of the System Console. According to this page:
https://www.altera.com/support/suppo...12014_911.html
I can run a simple GUI with the System Console. The minimal Example on the page works once, so when I run it in my script I get this output:
Code:
% source my_script.tcl
error: invalid command name "???"
while executing
"??? button .b2 -text {World} -underline 0"
(file "my_script.tcl" line 5)
invoked from within
"source my_script.tcl"
Ok there might be something wrong with the text, but that is not the problem at the moment.
When I try to run it again, suddenly something is wrong:
Code:
% source my_script.tcl
error: can't invoke "button" command: application has been destroyed
while executing
"button .b1 -text {Hello} -underline 0"
(file "my_script.tcl" line 3)
invoked from within
"source my_script.tcl"
I would be very happy, if someone could help me with that.
Best Regards,
Philipp

I'm trying to follow this tutorial to generate a preloader for my Terasic DE0-NANO-SOC development board:
http://rocketboards.org/foswiki/view...sLab1Preloader
I'm using the 15.1.0.185 builds of Quartus Prime Lite Edition and SoC EDS Web Edition on a Windows 10 laptop with built-in SD card reader and micro-SD adapter. I keep trying the following step where the final D is my micro-SD drive letter:
Code:
alt-boot-disk-util -p preloader-mkpimage.bin -a write -d D
I always get:
Quote:
device open failed!
The SoC EDS command shell is able to navigate to /cygdrive/d without issue and I can browse the contents of the micro-SD card using Windows explorer. I loaded the DE0-NANO-SOC image described by the tutorial as my starting point. The tutorial uses version 15.0. I tried using components built with 15.1.0.185 and had the same issues as well as a different micro-SD card. Has anyone had success/issues using alt-boot-disk-util with these software/OS versions?

Hi,
I'm trying to create my first HPS system on a C5 Soc board from Terasic.
If I create a system with one JTAG2AVM bridge (called fpga_console in picture qsys_causing_no_error.png) I can run the script shown below, and the leds lit according to the number writen.
Code:
set jtag_master [lindex [get_service_paths master] 0]
open_service master $jtag_master
master_write_8 $jtag_master 0x00010040 1
master_write_8 $jtag_master 0x00010040 2
master_write_8 $jtag_master 0x00010040 3
master_write_8 $jtag_master 0x00010040 4
close_service master $jtag_master
The documentation that I follow from Terasic however tells me that I need to add a second JTAG2AVM Bridge and connect that one up to the f2h_axi_slave (called hps_console in picture qsys_causing_error.png)
When I do this and try to run the script above again, system consoles timesout with an error (see system_console_error_message.png).
I don't understand that this connection, has influence on the fpga_console, that it not connected at all to the HPS or the hps_console.
Any advice?
Is this connection putting the HPS in reset perhaps?
Rgds,
Kimberley

Hi,
I'm conceiving a new Cyclone V E based board implementing a 5CEFA7F23, a DDR, a SRAM and a Flash memory. I wish to configure my FPGA with Asx4 configuration, so I need a QSPI NOR Flash for my board.
Is the EPCQ the only device supported for this type of cofiguration ? Or a QSPI Flash memory from Spansion, like S25FL family, or Micron, like MT25Q/N25Q families, works too ? In fact Altera's EPCQ is quite expensive to be simply a QSPI Flash.
I found these application notes from Spansion and Micron talking about, but only up to Cyclone IV:

I need to modify an old project, developed with Quartus II 9.0 on a Stratix III, that contains a DDR2 controlled made using an altmemphy IP. So I installed the software, made the modifications and recomplied it. Unfortunately it is not more possible to generate a working programming file, because with the current Quartus II license file (dated august 2015), the license to compile this IP is not more present. Only a time-limited programming file is generated. So I have the right software, I have a working license, but I cannot use an IP whose license was previously included into the base software. Why?
I configured the license server with the old (expired) license file, and it was possible to compile and generate the programming file, but this cannot be a solution because we have floating licenses running on a server, that is used by many designers.
I tried to run multiple services from the flexlm tool, connected to different IP ports. In this way I could connect to an alternate server port only when I am working on this old project. It works, but after some time, the altera license daemon stops with an error, because it detects another daemon running. I can understand why: if this would be possible, I could easily multiply my licenses, and this is not allowed.
I cannot force the whole company to use an old license (having puchased a new one) file only because I need it... so my question is: is there a "legal" way to do this?
regards

Hello all,
I'm interfacing my DE0-nano with a micro-controller using SPI protocol. The FPGA is acting as a slave and the Micro-controller as a master.
All the input signals of the SPI (MOSI, SCLK, CS) are synchronised with the FPGA clock (100 MHz)
Everything is working fine with low SPI clocks.
Now i'm trying to increase the speed of the SPI(SCLK=5 MHz) but the MISO DATAs are shifted.
With my logic analyzer, I detect the problem. In fact, in the falling edge of the SPI clock , data on the MISO line should be ready before the the next rising edge of SPI clock.But it is not the case.
The time that the MISO data required after the falling edge of the SPI clock is about (0.125 us). So if i want to get high speed communication, i must reduce this delay.
I'd like to ask for help of the experts of community if there is a way to do that.
Kind Regards,

Hi there,
I've got 2 questions related to how to setup my JESD Qsys IP for the TI ADS54J60 ADC.
- Is it correct to fill-in a data rate of 5 Gbps in the Qsys window with the configuration as shown below?
- (1 Gsps * 2 ADCs * 16 bits * (10/8))/ 8 lanes
- Is it correct to calculate the link clock as: 5 Gbps/40 = 125 MHz?
- I don't really understand where this 40 is coming from/based on.
Thank you for your help.
With kind regards,
Patrick

Please give me a link for "How to apply time constraint to counter"
Can not find any good explanation.
If counter consist of two or several parts
should i use multicycle for all elements (then 2^32 not acceptable in TimeQuest) or
should i use false_path and
Should I constraint only the the most changing bit or
not.
The counter of 64 bit can be as 4bit and 60 bit, or 4 parts by 16bits, or 2 parts by 32 bits or else.
