Estimate Memory

Parent Previous Next

The analysis engine, em, allows you to subsection your circuit without running an analysis to get an estimate of memory use.

      1.  To estimate memory, select Analysis - Estimate Memory from the main menu in the Cadence Virtuoso Interface window.

You may also estimate memory by clicking on the “Estimate Memory” button in the Cadence Virtuoso Interface main window.

      1.  If a query window appears asking if you wish to translate the circuit, click on yes.

A simple status popup appears to indicate that the circuit is being subsectioned.

When the subsectioning is complete, the memory use estimate and the subsectioning information, listed by level and total amounts, is displayed.

      1.  Click on the View Subsections button in the Estimate Memory Results window.

Sonnet’s session window is opened on your display, then the subsection viewer tab is opened displaying the subsectioning. Note that since the default metal fill type was conformal, the majority of the subsectioning is green indicating Conformal Mesh.

      1.  Select File - Exit from the main menu of the Sonnet Subsection Viewer to close Sonnet.

The Sonnet session window is closed.

      1.  Click on the Close button in the Estimate Memory Results window.

The Estimate Memory Results window is closed.
