Open Schematic Viewer

Tools Supported: FastScan and FlexTest

Scope: All modes

Usage

OPEn SChematic VIewer

Description

Invokes the optional schematic viewing application, DFTInsight.

The Open Schematic Viewer command opens a DFTInsight schematic display window. If you issue the Analyze Drc command, the Add Display Instances command, or the Analyze Fault -Display command (in FastScan only) prior to the Open Schematic Viewer command, DFTInsight displays that netlist upon invocation. Otherwise, the schematic display window is initially empty.

By default, DFTInsight looks for the netlist at the following location:

$MGC_HOME/tmp/dfti.<process#>/ipc/display.gn, which is also the default location where FastScan and FlexTest place the netlist. You can change this default location for all three tools by using the Set Schematic Display command.

DFTInsight handles these two interrupt types as follows:

∙Terminating a Large Schematic Generation: When DFTInsight generates a large schematic, it may take several minutes. You can terminate a lengthy generation by entering Control-C in the DFTInsight window. This causes the display to revert back to the previously-viewed schematic. If you enter Control-C multiple times, the first Control-C terminates the schematic generation as described; DFTI traps and discards all others.

∙Terminating a Dynamic View or Select Area: When using the mouse to perform a view area or select area by using the press-drag-release or click- move-click methods, you can terminate the dynamic view by pressing the Escape key. This leaves the schematic in the state it was in prior to initiating the view or select area.
