Custom Wire Load Model
Hi,
I need some help in generating a custom wire load model. I've looked at the application note from synopsys. I do have a block routed in Astro and I've generated the SPEF file from it. I can load the design in Primetime and can annotate the parasitics from the spef. But I'm having trouble wrting the physical annotations. the write_physical_annotation command requires a cell name. I want the physical annotations for the complete design. If I do get_cells in PT I get instances of all the standard cells.
Can someone help ?
Thanks!
