# General Notes
* logical wrappers instantiate hard array
* SDR: use multiple hard array instances to add ports
* DDR: use early/late pulses to double read/write ports
### DDR Implementation
* strobes are generated from clk based on configurable delay parameters
## Test site arrays
* 2R1W, SDR - this is the sdr hard array and simple logical wrapper using single clock
* 4R2W, DDR - this is the ddr hard array and double-rate logical wrapper generating early/late pulses
### Configuration options
* SDR clock frequency (external to logical array)
* DDR clock frequency (external to logical array)
* SDR Pulse Control
* DDR Pulse Control
