Generating firrtl IR with Top circuit as RocketTile

[­이신우 / 학생 / 전기·정보공학부]

Hello. I am an undergraduate student studying Chipyard SoC Rocket. I am having a hard time generating firrtl IR of Rocket chip.

Whenever I want to build firrtl, the Chipyard wraps the circuit with TestHarness, therefore leading to firrtl IR with top circuit TestHarness. I just want to generate the RocketTile Circuit firrtl IR, and I don't know how to set up.

How can I handle this problem?

I am very open and thankful for any advices.

Hi, 

Can you give more insight into what you will do with the generated firrtl IR? Are you using CIRCT? For most of my work I was able to not generate the generation, but then just pass the appropriate generated firrtl IR module to a specific compilation pass.
