Hi everyone!
I have the following problem:
I made a design with PCIe, I²C, SPI and a SRAM-Memory.
The I²C- and SPI-Cores are made by myself and connected to the PCIe HIP with some PIOs. The SRAM is connected via the Generic Tri-State Controller in QSYS.
Now I wanted to use the LAI to route some signals to a debug-port to check them in an oszilloscope.
But everytime I implement the LAI into my design, the I²C- and SPI-PIOs show wrong Values and after a few reads (with "pci_debug") on them my whole Computer (Debian) crashes so I have to do a hard power off.
This doesn't happen if I read on the SRAM. I can even measure the signals of the SRAM on the Debug-Port.
Are there any known issues with the LAI?
I use Quartus 12.1 SP 1.33
