I am facing issues with Virtuso Layout Editor ( IC5141-sub-version 126.96.36.1990.6.151) in my machine.My layout is having a lot of transistors ( like SRAM or DAC) in a small area.While
doing zooming-in or zooming-out of the layout ( i.e. EDIT in place EIP
) of the cell, it becomes slow ( 2 to 3 seconds) for the layout-window
to settle to the actual final stage.This is becoming very painful and irritating while doing the complex layout.
Can anybody please tell why this is happening. How it canbe made faster.
Maybe your Filter Size settings have been set too small (Options->Display in the layout editor). If I have it set to the default of 3 (with empty as the style) my small chip layout in 5141 redraws in a fraction of a second. If the filter size is set to 0, then it takes 3-4 seconds. Even with 1 as the filter size it takes less than a second (this means don't attempt to draw anything smaller than a pixel).
This might also be dependent upon you using some kind of X display tool (e.g. VNC, EoD etc) - I was trying this with a local X server on my Linux laptop.
