>> Have you looked at Xcircuit? Yes. The difference is that this is a text-based language with support for type checking so that you can't accidentally connect incompatible signals. It has some nice features for creating complicated structures. >> description language compare to that and to verilog? (I am imagining it >> is at least translatable to verilog RTL...am I close?) It's designed for asynchronous circuits, so some of the constructs could be easily translated to verilog, others would be cumbersome. The big difference between it and languages like verlog/vhdl, is that it is purely a circuit description/"rtl-level" description language. So you can't express things that aren't synthesizable. For instance, you can't say something like: x <= #50 y (i.e. a delayed assignment). This makes the life of a synthesis tool a lot easier (IMHO). >> [jg]Is COSMOS open source? Must be good if Intel is using it... It's a compiled simulator with some nice features. Not sure if it is open source or not... it probably is. It was written by Randy Bryant's group at CMU. -Rajit
