Mentor v8.6_4 manual Analyze Drc Violation, ∙ ruleid-occurrence#

Command Dictionary Analyze Drc Violation

Analyze Drc Violation

Tools Supported: DFTInsight, FastScan, and FlexTest

Scope: Setup and Atpg modes

Prerequisites: This command operates only after the design rules checker encounters a rule violation.

Usage

ANAlyze DRc Violation rule_id-occurrence#

DFTInsight Menu Path:

Analyze > Drc Violation...

Description

Generates a netlist of the portion of the design involved with the specified rule violation number.

When you issue the Analyze Drc Violation command, the tool includes different simulation data into the netlist depending on the type of rule violation. Even though DFTInsight displays the simulation data, the gate reporting data within the tool session does not change, unless you use the DFTInsight Setup > GateReport >... menu option.

If you invoke DFTInsight before you issue the Analyze Drc Violation command, the viewer automatically displays the graphical representation of the netlist and marks key instances in the schematic view. Otherwise, DFTInsight is automatically invoked, displaying the netlist.

Arguments

∙rule_id-occurrence#

A literal and integer argument pair that specifies the exact design rule violation (including the occurrence) that you want to analyze. The tool traces the violation back to the probable cause and then the schematic viewer displays all the gates in that trace. The argument must include the design rules violation ID (rule_id), the specific occurrence number of that violation, and the hyphen between them. For example, you can analyze the second occurrence of the C3 rule by specifying C3-2. The tool assigns the occurrences of the rules
