PCIe (1.0a to 2.0) Virtual host model for verilog

pcievhost

PCIe (1.0a to 2.0) Virtual host model for verilog.

Generates PCIe Physical, Data Link and Transaction Layer traffic for up to 16 lanes, controlled from user C program, via an API. Has configurable internal memory and configuration space models, and will auto-generate completions (configurably), with flow control, ACKs, and NAKS etc.

pcievhost is bundled with verilog pcie link traffic display modules and an example test harness. Tested for ModelSim/Questa only at the present time, though easily adpated for VCS, NC-Verilog and Icarus (and has previously been running on these in the past).

More informaton can be found in the documentation doc/pcieVHost.pdf

make : link issue with 32 bits librairies and msys64 (64 bits)

Hi,
When executing make, the process generates an error for every library , like :

D:/msys64/ucrt64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible D:/msys64/ucrt64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../libstdc++.

etc .....

i changed the -m32 ARCHFLAG with -m64 (in makefiles) , but then i have a problem with modelsim :

D:/msys64/ucrt64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible D:/TOOLS/Libero_SoC_v2023.2/ModelSimPro/win32acoem/mtipli.lib when searching

Thanks for your support

Issue when make run at verilog/test

Hi Simon Southwell, I was able to execute the VProc example and had some problems with make run at verilog/test . The log is in attachment. Can you take a look ? there are some error like this :

/usr/bin/ld: cannot find -lmtipli
/usr/bin/ld: skipping incompatible ../../../vproc/libvproc.a when searching for -lvproc
/usr/bin/ld: cannot find -lvproc
collect2: error: ld returned 1 exit status

LTSSM.Config_Complete issue

I think some miss-match about Specification of LTSSM. In Config.Complete state, TX need to send 16 TS2 and RX need to receive 8 TS2. But in C code ltssm.c, TX only send 8 TS2. You can see below picture :
