Hello, I try to check Area and Delay relationship. I guess if I increase the die area size while keeping the core utilization and compare the delay, I can see the area-delay correlation, right? But I don't know how to change the die size while keeping the core utilization. If I set both utilization and die area size in Config.mk, the die size doesn't seem to be reflected. How can I increase the die area size while keeping the core utilization? Is the only way to do this by manually entering die area and core area in Config.mk? #openroad

Either use core utilization to decide die size or go with manual die area. If both are given preference goes for core utilization.

Thank you 🥹!! I was confused about the core utilization and the utilization in 'Design area 191262 u^2 30% utilization', what do I need to add to the config.mk if I want to make this 30% utilization around 80%? I'd like to fix the utilization around 80% and compare it while increasing and decreasing the die size. @Vijayan Krishnan

The 30% utilization is the metric report, it just shows how much core area used/utilized at that stage. Share your config.mk

Thanks a lot ! I appreciate always. Oh, I thought that 30%utilization in 6_report.log shows how much core area used/utilized at final stage. Is that wright? If not, How can I check core/die utilization on logs? I used this config.mk

Try value of CORE_UTILIZATION with 60, 70,80... The die size will be small and core utilization increased

I tried CORE_UTILIZATION 60, but there is an error like this.. so i put place_density on config.mk but nothing changed. @Vijayan Krishnan
