Download and compile <a href="https://sourceforge.net/projects/xschem/">
XSCHEM </a>. The installation process is somewhat non-standard, and it
is also possible to run XSCHEM from source, without installation; please
refer to the installation section in README.TXT for more details.
<p>
First draw the schematics using XSCHEM.
<p>

<p>
Then set the netlist output format to tEDAx: options menu, tEDAx netlist.
<p>
Then click on the Netlist button to get a tEDAx file written. If the
file name of the schematics is nand, the result will be written as
<a href="nand.tdx"> nand.tdx </a>
<p>
In pcb-rnd, open the file menu, import, then select the submenu for
importing schematics from tEDAx:

<p>
After selecting the file, the netlist is loaded and all footprints are placed.
The process from this point is the same as with any other import:
disperse your subcircuits and optimize the rats nets with the key sequence
{c r}.
<p>

The import step can be done from the command line using the LoadTedaxFrom()
action.
