who can give the flow of custom ic design.
how to use the ic 5.0 of cadence. ?
how to use it to design a small project?
tnx

1. get all the process files from foundry;
2. USe these files to build your library ( for schematic and layout);
3. draw your schematic in cadence;l
4. run simulation using Cadence/ hspice/synopsys etc;
5. draw your layout according to your schematic.

 

[Hughes]

5.1 Draw layout
5.2 DRC/LVS verification
6. Layout parameter extraction / Parasitic resistance extraction.
7. Do post-layout simulation.
8. If post-layout simulation reveal some problem, go to step 5 or step 3.

as I know this topic is posted several times so far; BTW, here is a good answer:

BEST!

The first thing is SPEC. then flow 1 to 8

are there any places which can do CMOS 0.25 or even larger cheaply and package it too? Sometime ago I read that prices have fallen down to the level where hobbyists can create custom ICs, and I just wanted to know where?

yeah, you can check th net. There are some founderies which are doing this kind of work. But they have some rule that whatever you give them for fabrication, they claim some rights over it.

Not sure about this. Most foundries charge 20K USD for 0.25um. If you do not use their libraries they cannot claim any IP rights. Chartered Semi have a freeware type policy - no IP rights to their libraries, TSMC are the opposite. I doubt any hobbiest could afford a chip run in a foundry.

no but you can run a chip at mosis for $3000 US for about 20 pcs. only rule is mosis does not take the guy off the street - you need to be part of a company or university. probably making up a company (ooh, a pre-IPO startup) is good enough. get incorporated for $20, and call up mosis. they have old cheap AMI processes and very high speed, very expensive IBM processes too.
