High Speed Option:
Manage constraints associated with High Speed nets
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)
- nteractive 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
- Daisy Chain rules
- Pin to Pin topology
- Min/Max length rules support
