EDI 14.13 crashes with SEGV during placeDesign

marten

Hi there,

we are using Encounter v14.13-s036_1 (64bit) for P&R of our Designs. When running placeDesign on a big network on chip design, encounter always crashes during placement of the design (see crash report below). P&R of smaller designs like a simple cpu core works fairly good, so what could be the reason of this and how can we fix this issue?

....
