In this [Nature Paper](https://www.nature.com/articles/s41586-021-03544-w), authors have used Ariane design with 133 memory (256x16, single ported SRAM) macros as one of the testcases. We noticed synthesizing the available Ariane netlist in [lowRISC](https://github.com/lowRISC/ariane) GitHub repository with 256x16 memory results in Ariane design with 136 memory macros ([Here](./Testcases/ariane136/) we show how we instantiate memories for Ariane 136). [Here](./Testcases/ariane133/) we show how we convert the Ariane 136 design to Ariane 133 design. So, we added these two versions to our testcase list.

MemPool tile design is another testcase and we will be adding MemPool group in this list.
Here we provide the detailed steps to generate the netlist for each testcase. This netlist is used for the SP&R runs. The directory structure is as follows *./Testcases/\<testcase\>/<rtl\|sv2v>/*.
-*rtl* directory contains all the required rtl files to synthesize the testcase.

- If the main repository contains only the SystemVerilog files, we add the converted Verilog file to the sv2v directory.
