Using the code the GUI uses

Michael Robinson

Cadence GUI's are bulky and clunky. I want to drive the behind-the-scenes code that Cadence GUI's drive.

For example, le0ViaForm. I can set the variables that are used in the form: le0ViaForm->viaMode->value="Stack" from skill.

But those variables don't exist until the form is called at least once. So the first time my skill is run, it errors.

Once the form has been initialized (manually), using the form variables is difficult because of Cadence's 'unreal time' timing.

Yes, I know about hiRegTimer. That's a kludge.

Driving the inputs to a GUI from Skill is like yelling at a driver on the freeway going 70mph to change lanes. 

How can I access to the real code behind the GUI's? Where is the reference to the code behind the GUI's?

  •  Thanks for the inputs, Andrew.

    Preparing to write an auto via placer using dbCreateVia, I've been looking at the via stacks that get placed with leHiCreateVia->Auto (or Stack). The routine places an instance of each via in the stack according to the definition from the techfile. The interesting thing is that the vias are attached to eachother. If you select one you select the entire stack. But I cannot see the connection mechanism in the db properties. In the past I've used a parent/child attachement method. But the parent/child nodes for these stacked vias are nil. How is the attachement being made?
