Importing netlist to Electric is very useful feature from point of view of IC-designer, though.

Using EDIF format instead of SPICE netlist typically helps to use geometrical information created by tool where the netlist was initially designed

Yet I can't import some of EDIF files created by Tanner tools :(

(attached an example of such a netlist)

Even after fixing manuallty "invalid character in model" error the process stops with more complex message.

Steven could you suggest what may be wrong with this file? I mean may be Electric does not support some extension of EDIF format used by Tanner or whatever... what is this extension

• Netlist (.net) in Electric VLSI - 4 Updates

Netlist (.net) in Electric VLSI

"Bárbaro Maykel López-Portilla Vigil" <barba...@gmail.com>: Oct 10 10:57AM -0700 Hi everyone: I would like to ask you the following: I have a netlist file generated in LTSpice (* .net) and I need to load it in Electric VLSI . My idea is not to make the schematic circuit in Electric VLSI again. Do you know how it could be done?

Steven Rubin <str...@staticfreesoft.com>: Oct 10 11:58AM -0700 Sorry, but this cannot be done easily. Spice netlists don't have any placement information. This means you would have to use Electric's placement tool, which would try to optimize things in a rectangular grid layout, probably not what you want. And it's not clear that Electric can read this netlist, although it does have other ways of importing netlists, so you might have to start by converting the LTSpice file, a lot of trouble.   It would be best to go to the original program that wrote the LTSpice netlist and see if it has some other interchange format that Electric could read.      -Steven Rubin   On 10/10/2020 10:57 AM, Bárbaro Maykel López-Portilla Vigil wrote:
