Spectra DO File

Spectra uses a DO file which contains constraint information

As shown in the below picture some of the user friendly features of my SKILL program are:

1. It contains identifications for Net Class as NCls and for Match Groups as MGrp. With this update any Match Groups with GRP_* name, will be displayed in the form.
2. The net quantity is also displayed alongside.
3. It will list out the Layers which are defined as type “Conductor” in the Cross-section.
4. Some custom check boxes for changing the Trace to Trace spacing etc.
5. If you try to select the corresponding Net class of a Matched group then the program will display a warning under "DO not select NCls:". It means you are not supposed to enable the routing on the corresponding Net Class. This is to be carefully done manually in the form.
6. The form type is flexible.
