Si_listers,

Jon Powell has knocked out a really nice tool for making simple schematics 
that we can share as text.

Consider trying to draw a simple series terminated driver, tx line, load 
capacitance and receiver in ASCII:

|>-^v^v^v---------------|>
                       |
                      ---
                      ---
                       |
                      V

Now, with Jon's tool we can do the same thing as:

LINE: blue 65.0 190.0 105.0 220.0 65.0 250.0 65.0 190.0
LINE: blue 105.0 220.0 115.0 220.0 120.0 210.0 125.0 230.0 130.0 210.0 
135.0 230.0 140.0 210.0 145.0 220.0 155.0 220.0
LINE: blue 230.0 190.0 270.0 220.0 230.0 250.0 230.0 190.0

LINE: blue 155.0 220.0 230.0 220.0
LINE: blue 200.0 220.0 200.0 230.0 210.0 230.0 190.0 230.0
PRIMITIVE: 0
LINE: blue 210.0 240.0 190.0 240.0 200.0 240.0 200.0 250.0

LINE: blue 180.0 270.0 220.0 270.0 200.0 290.0 180.0 270.0
PRIMITIVE: 2
LINE: blue 200.0 270.0 200.0 250.0
PRIMITIVE: 2

Just clip the text into a file and open it with the sidraw.tcl script, 
available from the si-list web site ( or soon to be courtesy of Ray ).

Regards,


Steve.
