Additionally, below are the solutions published in recent months which customers viewed the most. I hope you enjoy these highlights!
Adding decap cells near clock buffers or flip-flops
Provides a script to place decoupling capacitors (decap cells) near clock tree buffers or even flip-flops. These cells can have a high current draw so inserting decap cells minimizes the current draw effects.
Script to convert config file to global variable file for init_design in EDI 11
The Design Import flow in EDI 11 uses global variables in place of the config file. This solution provides a script for converting the EDI 10.1 config file to a global variables file. It also updates your environment to MMMC if needed.
Step-by-step through a top-down hierarchical design flow
An easy to follow description of the steps to import a large design with blackboxes and go through a top-down hierarchical partitioning in EDI System.
