The unique workflow-driven design environment and comprehensive simulation engines allow you to quickly access and perform the analysis needed to meet your design needs. As your analysis requirements increase, it is easy to add additional workflows all within the same common UI.

Signal Integrity

Impedance

Identifies the source of reflection and noise by detecting impedance discontinuities and ensuring adherence to defined impedance constraints.

Reflection

Prevent signal degradation of critical nets due to overshoot, undershoot, and ringing by identifying reflections caused by mismatched impedance.

Coupling

Identify critically coupled traces within the PCB layout canvas to ensure adequate spacing and optimal signal quality.

Crosstalk

Easily determine interference caused by unwanted capacitive, inductive, or conductive coupling from one circuit or channel to another and improve signal quality throughout your design.

Return Path

Prevent divergence between ideal simulation and measurement by analyzing and identifying return path discontinuities to ensure uninterrupted references and an optimized return path.

Power Ground Noise

Provides measured indication of switching noise (and other types) on specific power/ground traces & shapes to reduce noise on other signals attached to the same plane.

TDR/TDT

Easily check the signal’s propagation, reflection, and impedance discontinuity by step pulse response which can better show voltage and impedance variation with time.

Serial Link (PCIe, USB, etc)

Easily model, simulate, and analyze topologies to evaluate signal integrity performance for complete serial link interfaces.

Parallel Bus (DDR)

Provides full time-domain analysis for parallel bus protocols and supports a variety of IBIS and AMI protocol setups, including the newer/faster protocols reliant on serial channel methodologies, to determine performance compliance.

S-Parameter Model Extraction (Channel)

Create realistic simulations with the easy and convenient extraction of S, Z, and Y parameters of multiple port networks that model package and board structures.

Power Integrity

IR Drop

Ensure proper power levels are delivered to devices through single-Board, multi-board, or package IR Drop analysis of the static power delivery system on PCB from multiple VRMs to CPU and DIMMs.

Resistance Measurement

Determine power loss through analysis of the DC resistance from a source to a load.

Resistance Generation (Measurement and Network Model)

Analyze system-level power loss for your entire PDN through the generation of a resistance network matrix based on the terminals specified by the user.

PDN Impedance Checking

Quickly identify high resonance, which may cause EMI issues, by analyzing adherence to target impedance.

Capacitor to IC Device Loop Inductance

Quickly evaluate the effectiveness of capacitor locations by computing the loop inductance of each capacitor observed from the given devices on the same power rail to ensure adequate power can be delivered when required.

IC Device Power Pin Inductance

Identify weak pins by measuring individual inductance and analyzing the capacitors placement effect on pins.

Best Capacitor Location Estimation

Determine the best location for capacitor placement to reduce resonance within the PDN which can cause EMI radiation.

Decoupling Cap Optimization

Automatically evaluate the board to define optimal decoupling capacitor selection and placement based on design goals (form factor, price, PDN robustness, etc).

Pin Location Effectiveness

Improve pin effectiveness with the easy detection of high resistance between the source (VRM) and load (pin) to reduce the likelihood of overheating.

Resonance

Prevent electrical spikes by identifying resonant modes between predefined frequency ranges.

Noise Coupling

Determine the effects of external power delivery, conducted emissions, and coupling paths to reduce noise on the PDN.

E/T Co-Simulation

Easily solve both electrical and thermal equations simultaneously through single-board/package or multi-board/package 3D finite element methods.

Package Thermal

Ensure adherence to JEDEC standards through the easy extraction of thermal parameters such as lead frame packages, BGAs, wire-bonds, package-on-package (POP) and system-in-package(SIP), flip-chip packages, and more.
