Hello @Vinayakamk, we are glade that you are finding Lighter helpful. There are two ways of integrating Lighter into any version of Yosys:

1. Follow the How To Use instructions in the Readme. ---> This will basically wrap Lighter as a Yosys plugin and automatically insert it into your system.

2. Lighter is also integrated with the yosys-f4pga-plugins repo where you can also install the clock gating plugin into Yosys along with a collection of other helpful plugins. Follow the instructions in their Repo for more details.

and also i have doubt,do i need to do to plugin every time.if i close terminal. im confused as i open other terminal with same directory where i have installed minconda,i got this error

[kanndil]

Yes exactly. In the case of the first option, you must use this command every time to insert the plugin into Yosys. yosys -m cg_plugin.so your_script.tcl And cg_plugin.so file must exist in your working directory. Which is generated using the following command: yosys-config --build cg_plugin.so clock_gating_plugin.cc

If you choose to use the other option, that is using this repo yosys-f4pga-plugins repo, you would need to install it only once into your system.
