sf-slack4<sdamghan> Hi all, Is there anyway to specify .input and .output for a sub-circuit in Yosys BLIF output ?18:33

sf-slack4<sdamghan> Example:                  assign q = a + b  After "proc; opt; memory; write_blif $PATH;" Yosys generates the following information for the add operation:                  .names $undef                  .subckt $add A=a B=b Y=q                  .end  I'm wondering is it possible to generate the corresponding .model record for the above mentioned sub-circuit in Yosys, for instance something like this:19:25
sf-slack4.model $undef                  .inputs A B19:25
sf-slack4<litghost> FYI, the model in that case would be $add, not $undef19:43

litghostIt can and should do the right thing19:45
sf-slack4<sdamghan> Yes, my bad. You are right. Anyway, is there any possibility?19:45
litghostIt may be skipping $add because of https://github.com/YosysHQ/yosys/blob/78684596dcd6e5c62d020d13480ed6d081c865bd/backends/blif/blif.cc#L656-L65719:46
sf-slack4<sdamghan> Thank you! I have just checked, however, Yosys does not generate the *.model* record related to the sub-circuit in the BLIF file. I have checked for addition, multiplication and memory. it should be noted that I achieved the same results with and without *-blackbox* flag for write_blif.20:05
