WebIt opens implemented design and writes out post-impl timing simulation netlist (write_verilog) and sdf (write_sdf). These files are then used for the timing simulation, along with the testbench and glbl. The flow is by design. So you see the netlist is produced based on the current design. When you set a different module as top, it's out of sync. Webpost-layout SDF is generated from DC or PT, after back annotating the extracted RC delay values and parasitic capacitances, to DC or PT. The post-layout values thus represent the … WebIf the write.SDF function is supplied with an SDFset object, then it uses internally the sdf2str function to allow customizing the resulting SD file.
