<ul>
|
|
|
|
|
<li>Don't want to wait a minute for a simple amplifier netlist.</li>
|
|
|
|
|
<li>Creating new components was way too complicated (you need a CDF, ask your CAD support and file a ticket).</li>
|
|
|
|
|
<li>Memory Hog, keeps growing until all Virtual memory exhausted, then crash.</li>
|
|
|
|
|
<li>Start your icfb session, go get a coffee, when back it's hopefully up and running.</li>
|
|
|
|
|
<li>One process handles all design windows. Process crashes, all work on all windows lost.</li>

|
|
|
<li>Many functions (search/replace/highlight and others) take way too long
|
|
|
|
|
to complete. Everything is done in skill.</li>
|

|
|
|
<li>Proprietary file format.</li>
|

|
|
|
<li>Computation intensive tasks should not be done in any scripting language (Tcl, Skill, Lisp, Python)</li>

Most Open source schematic editors are not for VLSI

<h3 style="text-align:left; margin-left:3%;margin-top:10px;">
|
|
|
|
|
<ul>
|
|
|
|
|
<li> Gschem (or its fork, lepton-schematic) and Kicad's eeschema, can not handle complex VLSI designs.</li>
|
|
|
|
|
<li> Xcircuit is one of the very few Open Source tools i found that is good for VLSI design.
|
|
|
|
|
Has very accurate graphics rendering, allows arbitrary rotations, uses postscript as schematic save format.
|
|
|
|
|
This makes scripted generation of schematic files a bit complex. Certainly one of the best tools
|
|
|
|
|
from graphic quality standpoint.</li>
