Virtuoso ruler resolution

Does anyone out there know how to control the ruler resolution?
Currently I have 4 decimal places, I would like to change to 3, as my
DB is set to 0.001 resolution. Thanx in advance! ( 4 makes no sense at
all. )

 

It appears (from a quick experiment) to have a resolution of a tenth of whatever
the snap spacing is. I don't think you can control it independently of the snap
spacing. This extra digit is probably a bit unnecessary.

Regards,

Andrew.

 

Andrew,
Thanks for the reply.
I work on XXnm designs, After a little looking around it has to do
with All Angle & Diagonal measurements.(the 4th bit does get used)
Here is the issue, When I measure somthing to be 99nm I see 0.0990 ,
(that would be the pico spot)
With drawing on 0.001 grid, the resolution is KILLER. I have to
measure everything!! The trailing 0 can be misleading.
(ie: was that 29nm or 290nm ?)
Maybe I could get a good skill hack to determine if orthogonal mode,
just use 3 digits to the right.
Any suggestions would be appreciated.
Thanxs in advance
Colin

 

Unfortunately the rulers aren't customizable with SKILL, as far as I know.

You could potentially use things like DRD to make it a bit less necessary to
measure everything, I guess. Or some people use an artificially larger grid to
make it easier to lay out - the loss of area is generally small compared with
the time it takes to lay it out!

Or some people use an

On this topic, the code from following thread can be handy : setting bindkeys to control the snap
spacing.

Stephane,
Thanks, we've had the grid under control for sometime now.
We truly are drawing & measuring on a 0.001 unit. Changing the user
units/DB units would be unacceptable.
Dropping the trailing 0 on the ruler is just a pain. ( numbers like
18nm 26nm 47nm ect....)
I'll look elsewhere for a solution.

Stephane,

Just something that came to me... You could draw 1000x larger. So you would get 18.0 or 47.0 which
is less confusing... Basically change the user unit from um to nm.

Good luck,
Stéphane
