Scheme to PDEF

Synopsys provides a binary utility, scheme2pdef to convert the Astro floorplan into a PDEF file for Physical Compiler. The scheme2pdef utility performs the following tasks:

1. scheme2pdef generates a scheme file dump.scm, that contains the procedure dumpEverything;

2. dumpEverything dumps the floorplan information into files in a specified directory (argument to dumpEverything);

3. scheme2pdef converts the PDEF file from the data dumped by dumpEverything, as below command.

scheme2pdef -tech ./library/ tsmc13fsg_6lm.tf -sitemap ./ sitemap -dumpdir dump -output fp.pdef

And the following data/files are the requirements to convert Astro floorplan scheme into PDEF

- Astro design database

- Astro technology file

- site map file


The difficulty is preparing the sitemap file. The sitemap file defines the unit title size for Physical Compiler, its width and height can be found in Synopsys physical library (.plib) or milkyway technology file (.tf).
