These days, a lot of digital design work involves little more than patching together a few highly integrated blocks. It seems as if everything is VLSI (and CPLD/FPGA). A lot is, but not everything.
Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...
VHDL and Verilog are hardware description languages, used to describe and define logic circuits. They’re typically used to design ASICs and to program FPGAs, essentially using software to define ...
