Hi Eugene, Thanks for the info... In fact I am using ROM as 3/8 and 4/16 line decoders - its quite a mission to create these from scratch. Also my hex keyboard uses ROM for decoding keystrokes to the relative 8-segment LED pin inputs. I've created the code in file and loaded the ROM(s) where ...

Hi Eugene, Yes it was about the shape of the gate. Thanks for pointing me in the right direction. Regarding the RAM I/O: Maybe you could have circuit blocks roughly as follows: Input block a 2-bit source pin (00 = keyboard, 01 = hard drive, and 10, 11 spare) a 8-bit file name pin (if source is 01 ...

Hi, Firstly may I compliment you on an awesome piece of software. It is an amazing learning/teaching tool. I would like to suggest the following: Primitive Gate (e.g. AND Gate) I/O orientation as per the splitter widget. I know you can do this by using a circuit block, but it is cumbersome. Standard ...
