DRC/LVS/NET Physical Verification

Guardian provides interactive and batch mode verification of analog, mixed signal and RF IC designs. Integrated with Silvaco's schematic capture and layout editor, Guardian efficiently performs design rule checks (DRC) and layout vs. schematic (LVS) comparisons.

Key Features

• Guardian is optimized for 64-bit Linux architecture
• Integration with Expert Layout and Gateway Schematic Editors provides a complete entry-to-verification design flow for analog, mixed-signal and RF designs
  
• Supports DRC/LVS/NET rule files translated from Dracula™ and Diva™
• Broad support of semiconductor process technologies through foundry-proven process design kits (PDKs)
  
• Fast, intuitive and hierarchical LVS debugging with cross-probing to layout and schematic views
  
• Guardian NET supports stress effects and well proximity parameter extraction
• Silvaco's strong encryption is available to protect valuable customer and third party intellectual property.

Guardian DRC Key Features:

Ease of Use and Adoption

• Rule file translators included to import runsets from Dracula and Diva make adoption easy
• Simple installation process does not require consultants to set up environment
• Easy navigation and visualization through graphical and text DRC error reports - intuitive for new users and experts

Productivity and Versatility

• Full DRC command set fits every design environment – local DRC for interactive usage and full-chip DRC in batch mode
• Optimized layer operations based on efficient memory management and advanced algorithms get the most performance from Windows, Linux, and Solaris platforms
• Connectivity-based DRC operations including antenna rule checking

Productive - Intuitive graphical DRC error debugging
in Expert Layout Editor.

Accuracy, Speed, and Capacity

• Supports 90 degree, 45 degree, and all-angle objects with no compromise in accuracy critical for analog and mixed-signal design layout
• Interactive DRC runs within Expert Layout Editor to provide fast DRC of a local area with errors stored in the same error database at chip level to maintain consistency
• DRC report database tracks hierarchical DRC run history
• Hierarchical DRC error reporting maximizes efficiency of layout debugging
• Multi-threading DRC offers dramatic increase in performance and capacity

Guardian LVS/NET Features:

Ease of Use and Adoption

• Intuitive hierarchical LVS discrepancy report significantly decreases time for error debugging
• Direct database links between Gateway Schematic Editor and Expert Layout Editor provides cross-probing as instant graphical discrepancy reports
• Black-box options for subcircuits provides for incremental LVS comparison in hierarchical mode and easy inclusion of IP blocks into the verified design at top level

Accuracy, Speed, and Capacity

• Accurate calculation of geometry-dependent SPICE parameters important for analog design with default or user-defined equations
• Precise identification of generic devices (e.g., transistors, diodes, resistors, capacitors), user-defined devices, and/or black-box subcircuits during LVS trace or both
• Efficient full-chip layout netlist extraction for any semiconductor process with unmatched performance

Cross-Probing: Interactive hierarchical cross-probing of
LVS discrepancy is clearly displayed.

Productivity and Versatility

• Hierarchical design database supports operations for flat and hierarchical LVS netlist comparison
• Handles any arbitrary shaped polygon geometry used in device formation
• Maximum preservation of original hierarchy for easy debugging during post-layout circuit simulation
• Hierarchical cross-probing of schematic netlist, extracted layout netlist, and physical layout
• Detects ERC violations (shorts, opens, dangles, and improperly connected devices) with convenient filtering options
• Supports MOSFET, BJT, JFET, MESFET, diode, resistor, capacitor, and parameterized user-defined devices
• Guardian LVS is multi-threaded for hierarchical runs only

Net Tracing follows nets and devices between layout
and schematic netlist.
