SIMULATION AND ANALYSIS

Perform analysis to optimize high-speed performance, to solve and verify critical PCB design requirements.

SIGNAL INTEGRITY

 

The eCADSTAR Signal Integrity and eCADSTAR Signal Integrity Advanced modules add sophisticated Signal Integrity Analysis capabilities to eCADSTAR.  These allow for simulation in the Schematic (pre-layout SI) as well as in the PCB Layout (post-layout SI).  Simulation is consistent, intuitive and easy to use throughout the eCADSTAR design process.  Results are displayed in the same results viewer regardless of where the simulation is initiated.

  • Planning and realization of impedance controlled PCBs in the eCADSTAR design process (through integrated fieldsolver) avoiding the need of external tools for impedance control (and potential transmission errors).
  • Constrain and plan topologies (routing order/pin sequence) of your high-speed signals, avoiding reflections, over-engineering, and excess power consumption.
  • Check signal integrity to ensure that the appropriate signal quality and timing requirements (e.g. fast DDRx memory module) are met.
  • Browse and share (by import and export) of simulation models across different designs and users.

POWER INTEGRITY AND EMI

 

The eCADSTAR PI/EMI module adds sophisticated Power Integrity and EMI Analysis capabilities to eCADSTAR. Power integrity and EMI analysis are embedded into eCADSTAR. They share the same design data and simulation library used for Signal Integrity. Results are displayed in the same results viewer used for Signal Integrity Analysis and IBIS-AMI.

  • Investigate and analyze voltage drop (IR drop)
  • Analyze and display current distribution by signal by layer
  • Perform analysis with virtual design elements, capacitors to consider effects on impedance and study resonant frequencies, and decoupling efficiency

IBIS-AMI

 

The eCADSTAR IBIS-AMI module adds sophisticated IBIS-AMI Analysis capabilities to the eCADSTAR SI Simulation modules.

  • Analyze SERDES channels (e.g. PCI-Express Gen3+, HDMI, SATA, USB, etc.) based on IBIS-AMI models
  • S-Parameter characterization of the channel
  • Eye diagram results, BER estimation and bath-tub curvess
  • Import IBIS-AMI devices into the simulation library
