Virtuoso Video Diary: Why Split Symbols?

A large symbol with hundreds of pins is difficult to manage and makes a design messy. With more complex designs and advanced technology, splitting up blocks has now become a useful feature of any design.

The Split Symbols feature introduced in the ICADVM 20.1 base release in Virtuoso Schematic Editor provides a solution to easily and effectively manage large symbols by splitting them into multiple partial symbols. Split Symbols lets you split large symbol masters and helps in improving the legibility of the schematic. Large PCB and package schematics benefit from this feature.

Using the Split Symbols feature, you can reduce the size of symbols within a schematic. The pins can be logically categorized and placed within dedicated part symbols. This makes it simpler to place and manage a large number of pins. Also, it is easier to visualize, route, and trace the net connectivity, and the design connectivity remains the same.

Note: The primary use of this enhancement is in the Virtuoso MultiTech Framework flow.

Let's now see the various steps required to split a large symbol into multiple small symbols.

Looks exciting? Then play around with this feature in Virtuoso Schematic Editor and see how it works for you.
