#618 routing problem for my design New issue created by peijunh Hello. I am using OpenLane to run my design. I use to way to determine the size of my design, one is to use the following config to set the size of it manually

set ::env(FP_SIZING) absolute

set ::env(DESIGN_IS_CORE) "1"

set ::env(DIE_AREA) "0 0 1000 1000"

set ::env(CORE_AREA) "50 50 950 950"

This give me this error:

4873860343726c2be203ad8b9479fa5▾

cb9e3044fcc0f058d3c5b596b19dc9e▾

I then comment the AIE_AREA, CORE_AREA and use the default setting, which set the FP_CORE_UTIL to 50. But the result give me this error: [ERROR GRT-0118] Routing congestion too high. Then I set FP_CORE_UTIL to 30 to see if I can lower the congestion. But I get the error in the following figure: So is there any suggestion on why they are happening? Thanks!
