The incubator process just landed, it would be great to outline how CIRCT aligns with the new guidelines set out in that document. As you know, I’m personally very much in favor of this project landing, but am also have a conflict of interest, so I’d like to know what other community members think.<div class=""><br class=""></div><div class="">-Chris<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jul 4, 2020, at 3:29 PM, Stephen Neuendorffer via llvm-dev <<a href="mailto:llvm-dev@lists.llvm.org" class="">llvm-dev@lists.llvm.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><span id="gmail-docs-internal-guid-74a8d807-7fff-8a08-78b6-99bcf7722c77" class=""></span><br class=""><div class=""><span style="background-color: transparent; font-family: Arial; font-size: 11pt; white-space: pre-wrap;" class="">For the past several months, members of the ‘CIRCT’ group have been working to begin adapting MLIR for hardware design. We believe that this area would benefit from good open source infrastructure enabling research and, eventually, the next generation of commercial tools. We have collected several dialects and envision a number of lowering flows using these dialects. We have reached the point where we are ready to share our ideas more widely and would like to be considered as an LLVM incubator project.</span><br class=""></div><div class=""><span style="font-size: 11pt; font-family: Arial; background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;" class="">

We have weekly discussions with a group of about 20 people from Xilinx, SiFive, Microsoft, PNNL, ETH Zurich, EPFL, Stanford, and Cornell, and welcome additional contributions. This project is still early and we see many elements as highly experimental. At the same time, we feel that the only way to vet these ideas is to build larger systems which will likely take some time and community investment. The LLVM incubator process would be a good way to help us organize this effort.</span></div><div class=""><br class=""></div><div class="">Steve Neuendorffer</div><div class="">Xilinx Research Labs <span class=""><span style="font-size: 11pt; font-family: Arial; background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;" class=""><br class=""></span></span></div></div>
