Merge pull request #589 from litghost/add_bits_library
Add a Bits utility library.
2021-02-17 20:01:24 +00:00
Keith Rothman e189666a2d Add a Bits utility library.
This library captures use of __builtin_popcount and __builtin_ctz on
GCC/clang and hopefully handles the MSVC case.

Keith Rothman bb4fa7af5b [FPGA Interchange] Add Cell -> BEL Pin maps.
This also expands the FPGA interchange Arch BBA to include placement
constraints, but doesn't implement them yet.

gatecat c7c13cd95f Remove isValidBelForCell
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.

Keith Rothman d987bd2997 Add unknown handles to convert [0] to "[0]".
Tcl reads something like "set port [get_ports x[0]]" as "invoke proc 0
with zero arguments", rather than just "[0]".  To prevent exposing
non-Tcl users this, "[<number>]" just return themselves.
