Introduction to Floorplanning SKILL Functions
Virtuoso Floorplanner SKILL functions are not interactive. They accept information as parameters and return status codes when specific tasks are complete.
Floorplanning place and route functions exist at two levels:
A high-level menu function is associated with each menu command or bindkey to control the user interaction. High-level menu functions provide the interface that collects and validates information before it is passed as parameters to one or more low-level procedural access functions performing the requested tasks.
This dual-level structure allows error checking and alternative action. Each low-level procedural access function returns status information following task completion, allowing the high-level menu functions to examine the status and to take alternative action if errors occur.
Cadence recommends that you use the floorplanning SKILL functions in the order depicted in the associated flowchart.
