About csi_fuzzer.v. #332

Open bzambition opened 10 months ago

1.When I modify i0 and q0 in csi_fuzzer.v to half of the source code, why does the csi image not appear when I perform the csi experiment in "packet-iq-self-loopback-test.md"?( for example: assign i0=iq{iq[(2IQ_DATA_WIDTH-1)],1'b0,iq[(2IQ_DATA_WIDTH-2):IQ_DATA_WIDTH+1]} ) 2.Why does the iq_out in csi_fuzzer.v not expand the bit width when performing the addition operation, and the bit widths on the left and right sides are actually the same. Doesn’t this cause data overflow?
