ANSYS Designer SI

ANSYS DesignerSI is a set of specialized product suites for engineers designing various signaling architectures that include XAUI, XFI, Serial ATA, PCI Express, HDMI and DDR. This easy-to-use design platform integrates rigorous electromagnetic analysis with circuit and system simulation in a highly accurate design flow for gigabit communication and memory applications.

Using DesignerSI, you can leverage multiple signal-integrity simulation methods such as traditional transient, fast convolution, statistical and IBIS-AMI analyses in a single user interface. These methods utilize optimization algorithms, design of experiments (DOE), tuning, and post-processing for key signal-integrity metrics, such as TDR (time-domain reflectometry), BER (bit-error-rate), timing analysis and eye diagrams. The new solver-on-demand technology in DesignerSI allows you to drive electromagnetic simulators (ANSYS HFSS, ANSYS PlanarEM) and circuit simulation tools (ANSYS Nexxim and Synopsys® HSPICE®) directly from its layout-based interface. DesignerSI with solver-on-demand technology delivers the best-in-class design platform for signal- and power-integrity analysis.

components, including on-chip embedded passives, IC packages and PCB interconnects. These types of designs can be easily modeled in HFSS’ electrical layout environment while, at the same time, simulating for all 3-D features, such as trace thickness and etching as well as bondwires, solder bumps and solder balls. Geometry such as trace width can be easily parameterized and optimized using the integrated ANSYS Optimetrics tool in the HFSS for ECAD interface. Beyond the convenient electrical layout environment, HFSS includes a fast 2.5-D planar electromagnetic solver based on the method of moments. This provides the flexibility to use a fast solver optimized for planar structures in the initial design phase, and then turn to the reliable 3-D accuracy of HFSS finite elements for optimization and design verification. Signal integrity engineers use HFSS for ECAD to integrate within established EDA design flows to evaluate signal and power quality, including transmission path losses, reflection loss from impedance mismatches, parasitic coupling, ground bounce and radiation.
