Search for TTL or CMOS, there are 100's of logic gates. SN74xx or CD40xx will be a list of common types. It's a pretty major task.
Also check the TTL cookbook and CMOS cookbook by Don Lancaster.
Why would you want to write a simulator for parts that are slowly vanishing?
its not a college project. i have a drop and am killing the free time being productive. if things go well i can pretty much convince my profs to accept it as my fourth year BE project. i am doing electronics and telecommunication engineering.
i am trying to make a logic circuit simulator. am gonna make it for sequential logic circuit first and then for combinational.
Why not just get spice or proteus or any other decent simulator? IMO it's a monumental waste of time writing a logic simulator. Just collecting all the datasheets will be a pain. Anyways here's a list of common logic ICs (yes Google is your friend) http://consumertronics.net/TTL-Parts.htm 4000 series CMOS Logic ICs
Ive noticed that in Multisim you can view the model data for each component. It might be cheating a bit, but youd save a huge amount of effort by extracting the ICs and model data from existing sim software, decoding the model algorithims and useing that for codeing your own sim. Dont know where you would stand with copyright though. Perhaps its generic and not a problem, and only for your own use.
well if i select any one manufacturer then will it cover all the ics that there are?
like say ic 555. from what i know from my lab work is that ic 555 is made my one particular manufacturer. do other manufacturers also make these ics. i alteast wanna cover all the standard ones.
i know ic555 is not a logic ic. just gave an example
