Title: Color depth setup of Cadence
Post by danda821 on Apr 11^th, 2005, 2:32pm

Hi,

I am using Cadence icfb under unix system, using a DELL LCD monitor (1600x1200). When I set the color depth (using fbconfig command) to be 24, the speed of Cadence is very slow (esp. when doing the layout). When I set the color depth to be 8, everything is fine. But the color of the monitor is not good, esp. when using the web browser. It seems like Cadence can only work under 8 depth?

Thanks.

What version are you using? A lot of work has gone into improving speed when 24 plane graphics are used, but earlier IC50 versions were definitely slow with 24 plane graphics.

What type of workstation are you using? What graphics card? Certainly some linux drivers are a bit problematic too, which could be the issue.

Andrew.

I am running 2.0.33_USR2.34.8, using Sun Blade 2000 with XVR-100 graphic card. Thanks.

I found some machine (where the Cadence tool works fine) has two different visuals: 8-bit and 24-bit (check by run xdpyinfo). But mine has only 24-bit. I don't know if there is anyway to add more visuals to my machine. Thanks.
