[SOLVED] High fanout net synthesis in Innovus

[stevenv07]

Hello everyone,

As I know, at the placement stage, Innovus does HFN synthesis. However, I found that there are some HFNs as enable signal after placement. It causes big timing violation.

Is there any setting or commands for placement to perform HFNS in Innovus?

Thank you so much.
Steve.

it does it automatically if you use the place_opt command
