Hi,

I fixed the Horizontal Arc wire error and got a layout from VHDL.  The
Preferences - Technology - Technology Default options were not set at
mocmos.  After I changed Startup technology and Layout technology to use
for Schematics it worked.

Perhaps the defaults should be mocmos or did something that I might have
done change this.  This is the first time I checked out the Technology
options so any changes would have been automatic.

Hi,

I get the following error even trying the Silicon Compiler with the
samples library, tool-SiliconCompiler, tool-SiliconCompiler{vhdl}

=================================36=================================
Compiling VHDL in cell 'tool-SiliconCompiler{vhdl}' ... Done, created
cell 'tool-SiliconCompiler{net.quisc}'
Reading netlist in cell 'tool-SiliconCompiler{net.quisc}'
Placing cells
Routing cells
Generating layout
SC Maker cannot find Horizontal Arc wire in technology artwork
=================================37=================================

I had the mocmos Layers selected.

Thanks,
Dan

The Mudd chip was not generated automatically from schematics...it 
was laid-out by hand.

The Silicon Compiler in Electric is for gate placement only...not for 
placing individual transistors.  And even if you did get it to work 
on the schematics, the placement would be pretty bad because the SC 
is 20 years old and still thinks in terms of making rows with routing 
channels inbetween.
