From fd93697a2d4eca02fc5091a15a497f7a761f251a Mon Sep 17 00:00:00 2001 From: Alessandro Comodi Date: Mon, 10 May 2021 18:53:30 +0200 Subject: interchange: arch: do not allow site pips within sites During general routing, the only site pips that can be allowed are those which connect a site wire to the routing interface. This might be too restrictive when dealing with architectures that require more than one site PIPs to route from a driver within a site to the routing interface (which is something that should be allowed in the interchange).
