Tool eases waveform analysis

Antrim Design Systems Inc. says the re-launch of its Results Analysis and Display (RAD) tool automates analog design by making it easy to visualize the performance of analog and mixed-signal ICs. RAD version 2002.3 is a post-simulation analysis tool that allows cursors, annotations, and anchors to be overlaid on standard waveform charts.

Besides annotation, the charting tools support multiple y-axes and curve types.

RAD supports two design styles, said Antrim marketing VP John Wright. One is a command line interface, for power users who want to call out the results of Spectre or OmniSim with a Perl instruction. The other is a typical schematics-based visualization (like the Cadence Artist environment) in which the user can bring up a waveform by identifying a stimulus and probing points on the schematic.

The tool will support split panes with a different x-axis in each pane, said Don Walters, vice president of engineering. Users can drag and drop waveforms from one pane to another.

"The overlap supports debugging," Walters added. Certain panes can be docked to aid in the waveform comparison.

Printouts of the x-y plot annotations will support in-house design reviews, assured Walters. Like the best document processors, RAD records events and user-initiated changes and offers unlimited "undo/redo" capability.

The RAD tool provides an analysis platform for high-frequency phenomena, such as dense modulation schemes, as well as for analog transients. RAD is integrated with Antrim's Aptivia (a measurement engine based on The MathWorks' Matlab simulator). All of the interactions with RAD are logged into a Perl file, which can be customized and replayed.
