OpenCL library example1 - aocl-opt error

Hello!
I am interested in packaging VHDL code as a part of OpenCL library. I am trying to run the examples listed on the website https://www.altera.com/support/suppo...n-example.html

This is specific to example 1, but I get the same error for example 2 as well.
I have followed the steps in the Readme.html present in the package.

Code:
dg252267@is231451:/local2/library_example1/device/lib1$ ls
c_model.cl  div  double_lib.aoclib  double_lib.aoco  double_lib.h  double_lib.xml  dspba_library  rsqrt  sqrt
dg252267@is231451:/local2/library_example1/device/lib1$ aocl library hdl-comp-pkg double_lib.xml -o double_lib.aoco
dg252267@is231451:/local2/library_example1/device/lib1$ aocl library create -name double_lib double_lib.aoco
dg252267@is231451:/local2/library_example1/device/lib1$ cp double_lib.aoclib ..
dg252267@is231451:/local2/library_example1/device/lib1$ cd ../../
dg252267@is231451:/local2/library_example1$ ls

Can specify at most 1 positional arguments: See: /local2/is231451/intelFPGA_pro/16.1/hld/linux64/bin/aocl-opt -help
Error: Optimizer FAILED.
Refer to example1/example1.log for details.

dg252267@is231451:/local2/library_example1$ aoc -march=emulator device/example1.cl -o bin/example1.aocx -I device/lib1 -L device -l double_lib.aoclib --board alaric_v3_prod

Can specify at most 1 positional arguments: See: /local2/intelFPGA_pro/16.1/hld/linux64/bin/aocl-opt -help
Error: Optimizer FAILED.
Refer to example1/example1.log for details.
I have tried the command both with and without the emulator.

If I run aocl-opt - help , I get a list of available parameters that I can pass on. My issue is, the example1.cl does not use this command. And the device libraries are obfuscated code, so I cannot actually see where the aocl-opt is being called.


I have tried the multi vector add example and it executed successfully. I haven't tried the other 2 examples listed as they are for v17.0 and I am using v16.1.
I am targeting ReflexCES alaric Arria 10 board. I am running this example on Ubuntu 14.04.


Has anyone come across this error before? I welcome any suggestions.

Thank you!

Unable to simulate MAX 10 ADC

Hi,

I'm thoroughly stuck on simulating the MAX 10 ADC.
Tools: Quartus 17 Lite (and 16.1) + ModelSim-Altera 10.5b

Modelsim error:
# ** Error: (vsim-3033) C:/temp/ADCtest3/source/On_Chip_ADC/simulation/submodules/On_Chip_ADC_modular_adc_0.v(38): Instantiation of 'On_Chip_ADC_modular_adc_0_control_internal' failed. The design unit was not found.

Steps taken:
1. Create Max10 project with top level and testbench VHDL.
2. Use IP Catalog to create "Altera Modula ADC Core" and generate the HDL code, selecting VHDL synthesis and VHDL models.
3. Add the generated component to my VHDL
4. Add the generated .qip and .sip files to Project Navigator
5. Tools>Run Simulator Tool>RTL Simulation
6. Get several ModelSim error messages similar to the above.

I'm puzzled that I don't see 'On_Chip_ADC_modular_adc_0_control_internal' defined anywhere.

Does anyone know what causes this error?

(I'm using the IP Catalog, not Qsys, because I want to be able to wire up the ADC PLL myself. I do have the PLL.)

Thanks,
Rob

Cyclone V Clock Not Toggling

June 15, 2017, 6:44 am

Device: 5CGTFD9E5F35C7
Quartus Version 14.1

I am currently having problems with the on-board oscillator (CLK5p(U31)) not toggling when used as the clock source in Signal Tap(e.g. the 'waiting for clock' status). In my design this clock is only connected to a Qsys generated DRAM module. The outputted Avalon clock also does not toggle which is a result of the input clock not toggling. I have tried using different clocks such as the CLK10p from the X4 programmable oscillator and that did not produce the waiting for clock status from Signal Tap. But, this clock did not produce an Avalon clock that toggled. I also tapped the waitrequest_n(1 = bus can be accessed) output from the dma_module and that did not toggle. However, this is probably due to the internal clocks of the DRAM module not being generated for some reason. I have also made a simple counter and viewed the results with Signal Tap to test the clocks. I found that clocks from sourced from the programmable X4 clock work as predicted. However, the fixed oscillators such as CLK5p do not oscillate and give the 'waiting for clock' status.

I also verified that the Qsys module is configured for input clock frequency (125 MHz).

Also DRAM timing was not met for some address values. The input clock and DRAM clock output also have negative slack (-4.570 and -.470 respectively).

Any help would be greatly appreciated.

Hi,
I'm a new member of this forum. I'm a HW/FW designer. I'm developing a schematic based on ARRIA 10 SOC.
I choosed the 10AS048H434I3SG device (1152 pins, 35mm x 35mm). I saw there can be also 10AS048H435I3SG with the same package.
I read the package information datasheet and it talks about an opton 2 on the same package 1152-pin FBGA.
Can you please explain me the difference between option 1 an option 2?
thanks a lot!!!

I'm trying to create the necessary external logic to control a MAX10 ADC Control Core Only instance. The timing in figure 8 of the UG-M10ADC User Guide does not define the relationship between command_valid, command_startpacket, command_endofpacket, or command_ready. Also, what is the reference for the term "ADC soft IP clock"? Is this the same thing as "modular_adc_pll_clock"?

How to increase NIOS II Instruction Memory?

June 15, 2017, 4:13 pm

I have a Nios II/e system running on a Cyclone V with 64000 bytes on-chip memory. It runs with no problems until I add an additional function call to my code. It doesn't seem to matter too much what the function call is or where it is located in the code but it causes the program to freeze after download from the Nios II Eclipse IDE. I eliminated several unused variables in the code and that allowed one additional function call before encountering the problem.

I suspected that I didn't have enough on chip memory allocated. Running CheckElfSize.sh results in: text data bss dec hex filename
54464 1004 3908 59376 e7f0 ../software/09EO2.elf

I doubled the size of the on-chip memory in Qsys to 128000 bytes, reassigned base addresses, recompiled both the hdl and Nios code and still ran into the same problem. Absolutely no benefit to doubling the size of the on-chip memory. It sure seems like I'm running out of program memory but I can't figure out how to increase the size of program memory if doubling the size of the on-chip memory doesn't work. Searching through the Nios II documentation hasn't given me any easy answers yet. Thanks for any assistance anyone can give.

Hi,
I tried to compile a compution.cl file with aoc command to generate computation.aocx.
(The command line is aoc -v computation.cl -o computation.aocx)
But It failed to generate .aocx file and only .aoco file was generated.
With the -v , it showed the stage of compiling on the screen and the information is :

What's more, my OS is Windows 10 Professional , Quartus version is 16.1.1, AOC version is 16.1.0, and It generated .aocx file successfully Before with other OpenCL kernel file.
Why it failed to generate .aocx file? And what should I do to shoot this trouble?

Hi
I have downloaded this attached code.
This code pin assignment is not matching with our board pin assignment, so I just removed the .qsf file and run again to do the pin assignment as per our board.

Unexplained performance difference for same kernels

June 16, 2017, 2:08 pm
$

I have develop two identical kernels, with a single difference where the size of the for loop in one of them is higher than the other. Here are my two kernels, Kernel #1 and Kernel #2.

First Kernel:
Code:
__attribute__((num_compute_units(5)))
__attribute__((num_simd_work_items(16)))
__attribute__((reqd_work_group_size(256,1,1)))
__kernel void TestS16VfloatI1048576D32Form1MUnrol0U16(__global float *data, __global float *rands, int index, int rand_max){
        float16 temp;
        int gid = get_global_id(0);


        temp = data[gid];
        #pragma unroll 16
        for (int i = 0; i < 32; i++){
                temp = (float) rands[-1] * temp;
        }
        data[gid] = temp.s0;


}
Second Kernel:
Code:
__attribute__((num_compute_units(5)))__attribute__((num_simd_work_items(16)))
__attribute__((reqd_work_group_size(256,1,1)))
__kernel void TestS16VfloatI1048576D256Form1MUnrol0U16(__global float *data, __global float *rands, int index, int rand_max){
        float16 temp;
        int gid = get_global_id(0);


        temp = data[gid];
        #pragma unroll 16
        for (int i = 0; i < 256; i++){
                temp = (float) rands[-1] * temp;
        }
        data[gid] = temp.s0;


}
As it's clear in both kernel implementations, both acquire same amount of hardware resources and also both unfolding the loop with same degree. There are compiled as NDRanege and I deploy around 1 Million work items.
Now calculating the amount of floating point operations being done, I can see the first kernel can achieve 1.57 TFlops performance while the second kernel can achieve 4.37TFlops. I'm trying to come up with an explanation on how it's possible that increasing number of operation inside the kernel can increase performance, while keeping the run time the same?

I have an AXI component that only needs to read so it does not implement the AXI write channels. Using the component editor in Qsys this gives errors.

Any way around this? I guess I can create dummy AXI Write channel signals and tie off the outputs and not connect the inputs.

DE0 Cyclone V GPIO 1-Z switching, RN series

June 14, 2017, 3:07 pm

Hello, I am currently working with DE0 cyclone V now.
I am trying to make a circuit that constantly switches the GPIO pins between 1-Z ( high impedance state) at a specified frequency (ex: 900 kHz).
But when I measure the voltage signals between GPIO pins and ground by an oscilloscope, it shows that even when GPIO pins are Z state, there are still some voltage.
Looking at the schematics, I can see that the GPIO pins are not directly driven by the FPGA. There are a RN series between GPIO pins and FPGA pins, as illustrated in the following photo:


I tried to look it up but I couldn't find what is that RN series, and what are they used for ?
And I also see that GPIO pins are driven by a source voltage through a pair of Schottky Diodes as as illustrated in the following photo:


I don't get why they need to drive the GPIO pins by another source of voltage. Then when the signal comes from the FPGA, how can it pull down the value of GPIO pins to 0 ?

Does anyone have the schematics of the above RN series and the Schottky Diode array ?
Thank you so much!
