PaperPositPETop.sv output unknown state (xxxxx)

[chir-77]

PaperPositPETop.sv output unknown state (xxxxx). This is because of the FF in line 27 to line 30 has no reset value, which results makes the input of PaperPositPE to be xx. As a result, qPostAdd become unknown state in the first clock after rst=0, consequently qReg.data. Hence forth the output will be stuck at unknown state.

This is the FF which has no reset value in file PaperPositPETop.sv
always_ff @(posedge clock) begin
aInReg.data <= aIn;
bInReg.data <= bIn;
end
