|/ | | | | | | | | | | | There is no need to multiply item names, it is a rudiment of my very first addition to nextpnr. Fully compatible with older versions of Apicula. Note: the cosmetic changes in lines with RAM are not my initiative, but the result of applying clang-format. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

| * | netlist: Add PseudoCell APIgatecat2022-07-0816-49/+198
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | When implementing concepts such as partition pins or deliberately split nets, there's a need for something that looks like a cell (starts/ends routing with pins on nets, has timing data) but isn't mapped to a fixed bel in the architecture, but instead can have pin mappings defined at runtime. The PseudoCell allows this by providing an alternate, virtual-function based API for such cells. When a cell has `pseudo_cell` used, instead of calling functions such as getBelPinWire, getBelLocation or getCellDelay in the Arch API; such data is provided by the cell itself, fully flexible at runtime regardless of arch, via methods on the PseudoCell implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor in order to detect networks that will be routed in a special mode earlier. This makes it possible to mark the source of such networks as a global buffer, thereby removing their influence on element placement. In addition, timing classes are set for some cells.
