VLSI Project Proposal

 

Extend the SRAM compiler to support 2 Read ports.  This entails creating a 2 read port cell, making the compiler tile it, then adding more address decoders and sense amps.  A high metal layer may be necessary (M3) for the decoders of the 2nd port.  This project is half layout, half python compiler scripting.

 

 

* Denotes perceived difficulty, from low * to high ***

 

Basic Plan:

• •.*Understand Python script / study 1R/1W cell 

• •.**Create / Simulate 2R/1W standard cell 

• •.*Add 2R/1W option into compiler 

• •.*Make compiler tile the 2R/1W cell 

• •.*Figure out where to put address decoders / sense amps 

• •.***Decide which metal layer 2nd read port interconnects will be on, metal3? 

• •.***Have compiler wire interconnects for 2nd port 

• •.**Test / Debug  / validate 

Extended Plan:

• •.*Simulate with CACTI 

• •.**Try reducing area / power
