* Add remapping of DSP clk/ce/rst signals in a block.Adam Greig2023-01-041-0/+253
| | | | | | | | | | | | | | | | | | Each DSP block contains two slices, and each slice contains multiple MULT18X18D and ALU54B units. Each unit configures each register to use any of CLK0/1/2/3, CE0/1/2/3, and RST0/1/2/3 ports, and the ports are connected per unit (so for example, two MULTs in the same block could connect their CLK0s to different external signals). However, the hardware only has one actual port per block, so it's required that all CLK0 signals within a block are the same. Because the packer is in general allowed to combine two unrelated units into one block, it may end up combining units that use different signals for the same port, which would eventually have caused a router failure. This commit adds validity checks which ensure only unique signals are used per block, and adds remapping so that conflicting signals are automatically reassigned when possible and required.

* Remove isValidBelForCellgatecat2021-02-161-30/+6
| | | | | | | | | | | | | | | | | This Arch API dates from when we were first working out how to implement placement validity checking, and in practice is little used by the core parts of placer1/HeAP and the Arch implementation involves a lot of duplication with isBelLocationValid. In the short term; placement validity checking is better served by the combination of checkBelAvail and isValidBelForCellType before placement; followed by isBelLocationValid after placement (potentially after moving/swapping multiple cells). Longer term, removing this API makes things a bit cleaner for a new validity checking API. Signed-off-by: gatecat <gatecat@ds0.me>
