* Remove isValidBelForCellgatecat2021-02-161-1/+0
| | | | | | | | | | | | | | | | | 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>

| * nextpnr: Add base virtual functions for non-range Arch APID. Shah2021-02-051-84/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | This makes the Arch API clearer and also allows a base implementation of functions to reduce the amount of complexity to get a basic Arch up and running. Currently this only implements these for functions that don't return a range. Range-returning functions will require more work in order due to the current 'duck typing' approach (probably a struct that contains the range types combined with templating.) Signed-off-by: D.

* ecp5: Use snake case for arch-specific functionsD. Shah2021-02-031-62/+62
| | | | | | | 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>
* ecp5: Implement IdStringList for all arch object namesD. Shah2021-02-021-14/+12
| | | | | | | This is a complete implementation of IdStringList for ECP5; excluding the GUI (which you will have to disable for it to build). Signed-off-by: D. Shah <dave@ds0.me>
* ecp5: Proof-of-concept using IdStringList for bel namesD. Shah2021-02-021-5/+8
| | | | | | | | | | | This uses the new IdStringList API to store bel names for the ECP5. Note that other arches and the GUI do not yet build with this proof-of-concept patch. getBelByName still uses the old implementation and could be more efficiently implemented with further development.

* Move RelPtr/RelSlice out of arches into commonD. Shah2021-01-271-37/+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>
* ecp5: Switch from RelPtr to RelSliceD. Shah2021-01-271-61/+62
| | | | | | | | | | 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>
