If you keep up with various retro vacuum tube projects, you probably have run across [UsagiElectric] aka [David]’s various PCBs that he makes on his own Bridgeport EZ-Track 3-axis milling …read more Continue reading A Guide to Milling PCBs at Home
Most people who want to simulate logic ICs will use Verilog, VHDL, or System Verilog. Not [hsoft]. He wanted to use Python, and wrote a simple Python framework for doing just that. You can find the code on GitHub, and there is an ASCII video that won’t embed here at Hackaday, but which you can view at ASCIInema.
Below the break we have an example of “constructing” a circuit in Python using ICemu:
dec = SN74HC138()
sr1 = CD74AC164()
sr2 = CD74AC164()
mcu_pin = OutputPin('PB4')
sr1.pin_CP.wire_to(dec.pin_Y0)
sr2.pin_CP.wire_to(dec.pin_Y1)
sr1.pin_DS1.wire_to(mcu_pin)
sr2.pin_DS1.wire_to(mcu_pin)
print(dec.asciiart())
