* Remove isValidBelForCellgatecat2021-02-163-123/+94
| | | | | | | | | | | | | | | | | 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>

* Mark IdString and IdStringList single argument constructors explicit.Keith Rothman2021-02-043-6/+6
| | | | | | | | | Single argument constructors will silently convert to that type. This is typically not the right thing to do. For example, the nexus and ice40 arch_pybindings.h files were incorrectly parsing bel name strings, etc. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>
* ice40: Use snake case for arch-specific functionsD. Shah2021-02-037-50/+50
| | | | | | | This makes the difference clearer between the general arch API that everyone must implement; and helper functions specific to one arch. Signed-off-by: D. Shah <dave@ds0.me>

* Move RelPtr/RelSlice out of arches into commonD. Shah2021-01-271-42/+1
| | | | | | | The bba approach seems widely used enough that it's reasonable for this to become part of common code. Signed-off-by: D. Shah <dave@ds0.me>
* ice40: Switch from RelPtr to RelSliceD. Shah2021-01-276-149/+137
| | | | | | | | | | This replaces RelPtrs and a separate length field with a Rust-style slice containing both a pointer and a length; with bounds checking always enforced. Thus iterating over these structures is both cleaner and safer. Signed-off-by: D. Shah <dave@ds0.me>

| | | | | | It has not actually been implemented in any router for over 2.5 years and causes nothing more than confusion. It can always be added back if it forms part of a future solution; possibly as part of a more general database structure rethink. Signed-off-by: David Shah <dave@ds0.me>
