# ToySRAM 'shard'
* hard array is decomposed into custom/RTL macros:
* partial components
* 16x12 custom subarray
* RTL for internal logic
* full components (netlist-style)
* 16x12 custom subarray
* wordline decoder
* local eval
* i/o
## Compile
* 64x24 single array
```
# shard array, simple RTL
verilator --lint-only -I. -Wno-LITENDIAN regfile_shard_2r1w_64x24.v
# shard array, netlist
verilator --lint-only -I. -Wno-LITENDIAN -Wno-MULTITOP sky130_hd.v sky130_fd.v wordlines_comp.v regfile_shard_2r1w_64x24_comp.v
```
* 64x72 logical array
```
# logical array, simple shard
verilator --lint-only -I. -Wno-LITENDIAN -Wno-MULTITOP sky130_hd.v sky130_fd.v regfile_shard_2r1w_64x24_comp.v ra_64x72_2r1w.v
# logical array, netlist shard
verilator --lint-only -I. -Wno-LITENDIAN -Wno-MULTITOP sky130_hd.v sky130_fd.v wordlines_comp.v regfile_shard_2r1w_64x24_comp.v ra_64x72_2r1w_comp.v
