原创 High Speed Design

 The High Speed cost option is available for the PCB design editor. A rich interactive  toolset featuring constraint  based routing and including differential pair routing, interactive  net length (min & max) routing and indicators,  Serpentine routing and Spiral definition.

 Features :

• 
  
• Easy definition of high speed rules using Technology files
  
• Rules can be defined at Schematic stage by the engineer and automatically transferred to the PCB design
  
• Rules easily defined on a per net class basis
  
• Rules analysis checked using DRC

 Differential Pair Rules

Differential pair definition and routing DRC check and reporting Pin to Pin rules Gap definition rule Percentage % pair routing rule Length deviation rule Rule check for paired track but not routed paired Interactive routing of pairs using pair router mode Start/end/remove modes of operation Add pair mode to add 'cone' route to master already defined

 Net Length Rules

Net length rules definition (min & max length) Interactive net length rules during manual routing Visual net length indicators showing min/max and textural indicators Track length min/max rules and Pin to Pin rules Max number of vias rule Min/Max track width rule Via diameter rule Display of rules during interactive routing Display of Min/Max rules using dynamic octagons Display of rules in text with dynamic update Colour changes of rule indicators/text when inside and outside rule tolerance Rule text size defintion

 Serpentine Routing

Serpentine routing for 'focused' interactive routing patterns Min/Max amplitude track separation distance number of cycles cycle reduction and removal automatic obstacle avoidance additional length rule min/max track length rules obeyed

 Interactive Spiral Support

Spirals using intelligent rules supported Circular/square shape Gap rules defined Number of turns Inner spiral width defined Aspect ration for non-square shapes Corner radius defined for circular shapes Spirals can be made in Copper and non-electrical shapes Spirals can be created and saved within the footprint definition

 Daisy Chain Rules
