There are some basic setups before running synthesis. By setting “search_path”, designers do not need to specify the absolute paths of files; Designers needs to specify the target technology library as well as the link library to resolve all instances inside the design.

To run Topographical synthesis / production synthesis, physical data is required. The following example shows how to setup milkyway design library for DC-Topographical.

If this is the first time for loading physical technology data, user must create a Milkyway design library as a “container”. This is used to package up the reference libraries, the technology file and TLU-plus models for use by DC-topographical

The next step is to load an already existing design library:

This concludes the basic setups before running synthesis. In next post, we will cover the DC synthesis flow.
