Double Design Verification
|
|
| |
Double verification is the process of applying comprehensive and rigorous checks to ensure the integrity of your design from layout to artwork. Pantheon's on-screen WYSIWYG features allow you to check the design's PCB and manufacturing databases before the design goes to production, which can eliminate any costly errors before fabrication. |

Pantheon also includes flexible violation display so that any error can be quickly identified and corrected. Using the DRC Violation Report dialogs or the view by index option, users can pan through errors based on index number or category. |

Pantheon displays the error using red arrows and prints a message describing the specific violation. The double verification process improves design quality, shortens the development cycle, and reduces the risk of manufacturing delays due to re-design. Design Rule Checks (DRCs) verify the design on the layout side, using standard and/or customized design rules, including complete database DRCs for components, routing, net topology, fills, high speed, teardrops, testpoints, geometries, placement, and physical layers for a design. While designing, Pantheon interactively checks the database against these predefined rules, helping the user to create an error free layout. |

Double Verification refers to artwork verification, even after the layout has been fully verified by DRCs. No other design application in the industry offers this capability. The first pass of artwork checks is the Electrical Rule Checks (ERCs), which verify that all connections in the layout are also properly made in the artwork. This is done by creating a netlist exclusively for the artwork (called a node list) and comparing it to the layout. The resulting report includes net mismatches, shorts, opens, extra or missing pins, and extra vias. The second pass of artwork checks is the Manufacturing Rule Checks (MRCs). These are a set of customizable rules that check clearance, coverage, and power/wire violations from the manufacturing standpoint. Pantheon's manufacturing verification contains a complete matrix of object clearance checks, including verification of annular rings, antipads, and soldermask coverage. |
