@title

PROGRAM mentor_read: Converter for .NET files

@application external

@text

PCB netlist to ACFP converter. If a file comes from Mentor Board station

use this one.

@break

Looks for netlists in ASCII containing tags like:

@listing

NET

@text

Invocation

@listing

mentor_read <net_file> [ d ]

@text

If a lower

case 'd' is present as the second argument, the Bison parser

(interpreter of keywords and syntax) prints extremely verbose diagnostics.

@break

Normally the acfp file produced on standard output is redirected to a file e.g.

@listing

mentor_read file.net > file.acfp

@text

Will produce file.acfp from file.net.

@break

Following this it is necessary to run the output through Vertical again in order to

set up properties on nets (power and ground being made not routable for instance) using the

delete routable command. Alternatively the acfp file can be edited to set the net routing

flags for these nets.

@break

There are some hints in the netlist, where attributes of some nets are given. These will appear

as comments at the top of the .acfp file produced. These may help identify power and ground

pins.

@break

If the attribute is NET_TYPE and the value following is

@listing

POWER

SUPPLY

POWERS

GROUND

HI-CURRENT

@text

Mentor_read will automatically set any nets with any attribute set to be not routable. Use set

routable in Vertical to allow these nets to be routable.

@break

Netlist is commonly seen with a '.NET' or '.NETS' file suffix.

This format comes from Mentor Graphics. It also mentions Board Station in the header of the

file.
