Hi everyone,
    I have been scouring the internet looking for viable low cost CAD tools.  Currently I am using Cadence, but am looking for a new low cost tool to use for custom analog and I/O design.

Most of my experience has been with Cadence, Mentor and Tanner.  I have also worked with several versions of freeware tools, such as LTSpice (which I like a lot) to name one, and a few layout tools to accompany it.  However what I need is a proper tool suite for some future projects on advanced processes (<90nm) that would make analog design, simulation, layout and validation a little easier to use than piecing together freeware.
I am leaning toward Tanner as my next tool of choice (cost mainly).

What I am looking for are any recommendations members of this forum may suggest as a tool choice to consider.  I know of many tools out there but I have no personal experience with some of them.  Maybe some of you know of a few off the wall tools that have served you well.

 I am open to suggestions.

Thanks,
Stephen

MG,
 Thanks for the link.  There are a few tools here I have not heard of so it gives me some more research to do.
 Per your inquiry, it is important that I can still use base level verification flows such as DRC, LVS and some extraction.
 Yes, the designs do go thru a flow downstream, but customers do not like it when IP runs into DRC issues in their final assembly.  :(

 Anyway, I am still open to any other suggestions people may have for a quality tool.

Thanks,
Stephen

Thanks for the pointing to this possibility Joel.  I will check it out and keep this message board posted on what I find.

Even Tanner does not offer a simulator capable of running Verilog/VHDL (that I am aware of).  So if I find something, I will let you know.
