kaz, you're right about different implementation methods for the same logic finally ending up in the same gate level netlist. But in VHDL text books, it's usual to distinguish these methods systematically and to require the students to solve a given p...

2003, The System Designer's Guide to VHDL-AMSPeter J. Ashenden, ... Darrell A. Teegarden Chapter Functional Verification Warning example A tiny portion from an incorrect ASIC design is shown in fig.5.6. The designer’s intention was to detect the zero state of a down counter by way of ...
The actual NAND gate logic simulator, written in Rust, only occupies a small part of the overall codebase. Even then, it's still a laughably high-level abstraction. The Rust code is compiled to WebAssembly to run on a browser, basically stripping away the entire premise of running every ...
The OR gate between A3 and CSn maps the flip-flop and NAND I/O in different address spaces inside the same chip se- lect unit, which improves the setup and hold times and simplifies the firmware. The structure uses the microcontroller DMA (Direct Memory Access) en- gines to optimize the...
