What’s new in CADSTAR 15

CADSTAR 15CADSTAR users get a productivity boost with new features in CADSTAR 15.

CADSTAR’s P.R.Editor now supports impedance balanced routing that simplifies the implementation of high-speed interfaces. Engineers can easily route to JEDEC standards and meet DDR3 performance specifications. New features in Power Integrity Advance include adjustable gridding for common-mode voltage maps, decoupling capacitor improvements, and a common user interface for result display in all signal integrity and power integrity analysis tools.

Users will appreciate the GUI’s updated appearance with familiar ribbon-style navigation.

  • Modeless Item Properties Dialogs - combines functionality from the many Item Properties dialogs and allows the user to both see and modify data from the current design selection.
  • Ribbon-style GUI - CADSTAR version 15 offers an updated modern appearance with a new ribbon-style GUI.
  • Active HTML Reports - Design Editor pre-defined reports include hyperlinks back to objects on the design canvas.
  • Impedance Balanced Routing – for users of high speed routing; added to the CADSTAR Place and Route Editor XR5000HS bundle.
  • New Transmission Line Model - The time domain signal integrity simulator kernel supports a new lossy transmission line model.
  • Improved Eye Patterns – include automatic measurement of eye height/width and setup/ hold.
  • New Field Solver – supports trapezoids and more general shapes such as circles and triangles.
  • Power Integrity Advance Updates – updated with new features such as adjustable gridding for common-mode voltage map and more.

 

Modeless Item Properties Dialogs

The new Item Properties dialogue combines functionality from the many Item Properties dialogs, allowing the user to both see and modify data from the current design selection. It supports floating, docking and auto-hide functionality. This avoids repeated opening and closing of the dialogue when reviewing or updating item or shape properties, offering improved ergonomics, efficiency and ease of use.

Impedance Balanced Routing

For users working with high speed routing, the CADSTAR Place and Route Editor (P.R.Editor) has added support for impedance balanced routing (IBR). Compliant with JEDEC lead-in routing requirements for DDR3, the feature supports both single-ended and differential nets. This results in a reduction of signal reflections caused by impedance mismatch at junctions for H-tree and other branched topologies. IBR has been accomplished by extending per-layer route width and differential pair spacing control to the pin-pair level. IBR supports setting different route widths on pin-pairs within the net, rather than just one width for the entire net, resulting in a reduction of signal reflections caused by impedance mismatch at junctions. New reports for pin pair width errors and differential pair pin pair spacing errors help ensure routing complies with constraints. IBR is available with the XR5000 HS bundle.

New Transmission Line Model

The time domain signal integrity simulator kernel supports a new lossy transmission line model which overcomes the inherent stability and accuracy problem of the so-called W-model, which is commonly used in various simulation products.

Improved Eye Patterns

The efficient analysis of high-speed channels such as DDRx requires a more sophisticated Eye Pattern analysis functionality, considering a base and a strobe signal. The improved Eye Patterns include automatic measurement of eye height/width and setup/hold.

New Field Solver

CADSTAR version 15 includes a new field solver that can handle not only trapezoids, but also more general shapes such as circles and triangles. Based on Method of Moments (MoM), it is faster than the existing Finite Element Method for trapezoids. The new fields solver is used for all field solutions.
