nv_small verilator not building (missing fles) #293

Open nganjehloo opened 5 years ago

nganjehloo commented 5 years ago

Hello. I am trying to build nv_small with verilator. I've gotten two errors. The first was RAMPDP_80X17_GL_M2_D2 which i found and added to the verilator file list in the verif folder/ However I cannot find the which is the new error /NV_NVDLA_SDP_MRDMA_EG_lat_fifo_8x65 Is nv_small and verilator currently supported?

I ended up using nvdlav1 as that seemed a bit more stable along with nv_full. Still had issues. A -Wno flag needs to be changed because of some changes in clang. Also a compiler flag also needs to be added because of linker issues. Once you are finished building, most tests will run and pass except googlenet and alexnet. The provided test expects a particular value at some point from the csb despite the hardware actually handling that operation differently than what the test expects. The hardware returns a 1 when a 0 is expected. Check for details #219.

After fixing that, the default nv_full design should work through verilator. Hope this helps someone.

I had the same issue and it turns out those missing modules are in the /fifos directory. I end up adding these lines in my veriator makefile and it works:
