rtl codes signal problems

[crizy]

the path : hw/hdl/network/rdma/
the file : rdma_meta_tx_arbiter.sv

the rtl code at line 163 of rdma_meta_tx_arbiter.sv file,

 assign user_seq_in.data = {vfid, request_snk[vfid].req_1.len};

the request_snk[vfid] signal does not exist in rdma_meta_tx_arbiter.sv file, what is in the file is just req_snk[vfid],

so line 163 should be :

 assign user_seq_in.data = {vfid, req_snk[vfid].req_1.len};

the path : hw\services\network\hls\hash_table
the file : generate_random_table.cpp

the hls code at line 61 of generate_random_table.cpp file,
uint32_t maxKeyValue = pow(keyLength, 2) - 1;

should be :
uint32_t maxKeyValue = pow(2, keyLength) - 1;

Hi @crizy,

Thank you for noticing both of these. Can you please explain a bit what work-loads (protocols, numbers of instances, connections etc.) that you are using. These are obvious syntax errors that we will fix, but for some reason we don't encounter them in our applications. So we would like to understand if there are some other subtle issues for work-loads we may not be using.

Thanks!

Hi @bo3z ,

 the first rtl syntax errors (rdma_meta_tx_arbiter.sv) was reported when I synthesized the rdma_perf example using U250 FPGA device
 the second （generate_random_table.cpp）was discovered when I was reviewing the HLS code

Thanks @crizy for the explanation. Can you share your CMake configuration with us? We don't seem to be facing these issues on the U55C, so we would like to understand what's different other than the device (number of vFPGAs etc.)
