Hi during the openlane process, in the routing optimization I want to increase the number of routing optimization iterations, I try to change the ROUTING_OPT_ITERS but only allow me to change it to less that 64. Is 64 the limit or can be change to a bigger size?

It's a bug. Issue is already opened on openlane

perfect thanks

@Matt Venn @Ivan Rodriguez Do you perhaps know if this bug is resolved or not?

nope

not fix yet, I reduce the density and the default placement to reduce the number of iterations

Thanks, guys.
