I have found a partial solution to my problem. It looks like the
"set_app_var hdlin_sv_blackbox_modules {moduleNames}" command marks a module such that DC no longer includes an empty module definition (problem #1 above).
However, DC still removes the parameters (problem #2 above), now...
I have a parameterized Verilog module foo that I would like to black box during DC synthesis and be able to plug in a simulation-only module later on. Essentially, whenever I've instantiated foo in my design, I would like DC to pass these instantiations (with parameters) through to the mapped...
Looking at the source .lib in more detail, I guess my question is why doesn't Design Compiler pick up and use the "timing_type: minimum_period" constraint? I've tried modifying the "when" and "sdf_cond" parameters to see if it would help the behavior of dc_shell, but this doesn't seem to work...
I'm new to Synposys DC and I'm having trouble with timing analysis. Basically, I've got memories generated through TSMC's mc2-eu tool. Looking at the output .lib and simulation Verilog, they seem to be reasonable blackbox units. However, when I instantiate them and define/constrain a clock...
I figured out what the problem was. These two modules were in two different files and I was using the "file_read" command to bring them in. File_read performs both analysis and elaboration. Elaboration was tying the parameter to the default value for the child, so when the parent was...
I have parameterized Verilog that works in Quartus and Modelsim, but I'm having trouble getting it to work in Design Compiler. Basically, the issue is that if I instantiate a module with parameter other than the default value, I get the problem:
