cad/cascade-compiler g20200105.1 DragonFly

Cascade is a novel solution to the problem that FPGAs take a long time to program, with complex programs taking hours to be compiled to run on FPGA. Cascade is a first just-in-time compiler for Verilog. Cascade executes code immediately in a software simulator, and performs compilation in the background. When compilation is finished, the code is moved into hardware, and from the user's perspective it simply gets faster over time. Cascade's ability to move code back and forth between software and hardware also makes it the first platform to provide generic support for the execution of unsynthesizable Verilog from hardware.
