* Object Device Routing Resource Switch Block
|
||||
* This includes:
|
||||
* 1. a collection of RRSwitch blocks, each of which can be used to instance Switch blocks in the top-level netlists
|
||||
* 2. a collection of unique mirrors of RRGSBs, which can be used to output Verilog / SPICE modules
|
||||
* 3. a colleciton of unique rotatable of RRGSBs, which can be used to output Verilog / SPICE modules
|
||||
* The rotatable RRGSBs are more generic mirrors, which allow SwitchBlocks to be wired by rotating the pins,
|
||||
* further reduce the number of Verilog/SPICE modules outputted. This will lead to rapid layout generation
