For Ariane, we have two versions one with 136 memory macros and another with 133 memory macros. In both versions 256x16 single ported SRAMS are used.
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 test cases. 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 test case list.
MemPool tile design is another test case and we will be adding MemPool group in this list.
Here we provide the detailed steps to generate the netlist for each test case. 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 test case.
- If the main repository contains only the SystemVerilog files, we add the converted Verilog file to the sv2v directory.
