If you go to [1], then click on "view". The source code header of SilComp.java has on line 6:
* Silicon compiler tool (QUISC): control The source code has comments in it suggesting that the implementation may be self-documented in the source code itself. I don't recall ever seeing any other developer documentation for Electric, but if there was it may have been something only the internal development team at Oracle had access to. Dr. Rubin could probably answer if he was able to take after retirement and could provide to us such documentation, if it existed. There are Verilog source code files such as VerilogParser.java in the directory at [2]. I remember reading in [3] that a user's experience with the Electric parser was that it lacked handling for standard Verilog. The software developers have the following comment in VerilogParser.java line 36: * /** * A brain-dead, extremely limited verilog parser. In fact, it really * ** doesn't do anything except return a module name with it's port defintions. * ** * ** <P>Again, this is not meant to be a fully featured parser. It's error handling * ** is also not very useful. It is only meant to extract module names and their ports. */ * It would most likely be a nice addition if a user could contribute a modification to the source code to upgrade to the Electric Verilog for example to use the IEEE Standard for SystemVerilog [4].
