RE: Video Amplifier Version 3

["Keith Doxey" <ukha@xxxxxxx>]

Hi Mark,

GROUND PLANE.

Select Graphics Tool
change layer to "Board Edge"
draw the outline which should appear as a yellow line
TOOLS - Power Plane Generator - and then you can flood the remained of the
board with a layer of copper that automagically surrounds everything else.

Because there isnt an imported netlist with you cant select a net to
connect
it to so it will be isolated from everything else. You will manually need
to
connect it to ground at one point with a blob of solder.

Just tried it on the V1 board and it worked but it failed on the V3 board
with an error message. Might be a problem with my version of Proteus being
older than yours, or the file may be corrupt.

I am just about to upgrade to a higher level.

Keith
