Add properties page, move cell_gate and cell_word under a singular cell_index along with properties. Fix links accordingly. Also drop x-aware and x-output todos since they are resolved.

Gate-level cells
|
|
----------------
|
|
|
|
For gate level logic networks, fixed function single bit cells are used that do
|
|
not provide any parameters.
|
|
|
|
Simulation models for these cells can be found in the file
|
|
:file:`techlibs/common/simcells.v` in the Yosys source tree.
|
|
|
|
In most cases gate level logic networks are created from RTL networks using the
|
|
techmap pass. The flip-flop cells from the gate level logic network can be
|
|
mapped to physical flip-flop cells from a Liberty file using the dfflibmap pass.
|
|
The combinatorial logic cells can be mapped to physical cells from a Liberty
|
|
file via ABC using the abc pass.
