Alessandro Comodi 104536b7aa interchange: add support for generating BEL clusters
Clustering greatly helps the placer to identify and pack together
specific cells at the same site (e.g. LUT+FF), or cells that are chained through
dedicated interconnections (e.g. CARRY CHAINS)

Alessandro Comodi fd93697a2d 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).

gatecat 93e34b8754 interchange: Disambiguate cell and bel pins when creating Vcc ties
The pins created for tieing to Vcc were being named after the bel pin,
relying on the fact that Xilinx names cell and bel pins differently for
LUTs. This isn't true for Nexus devices which uses the same names for
both, and was causing a failure as a result.

This uses a "PHYS_" prefix that's highly unlikely to appear in a cell
pin name to disambiguate.
