| | | | | | | | 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) Signed-off-by: Alessandro Comodi <acomodi@antmicro.com>

* interchange: arch: do not allow site pips within sitesAlessandro Comodi2021-05-121-6/+0
| | | | | | | | | | | | 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).

* interchange: Disambiguate cell and bel pins when creating Vcc tiesgatecat2021-04-091-6/+10
| | | | | | | | | | | | 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. Signed-off-by: gatecat <gatecat@ds0.me>
