IFS Pro is a software package specifically developed for design engineers with high speed analogue simulation requirements involved in PCB, cable, connector, VLSI, and related interconnect media design. As datarates escalate beyond 1Gbit/s, the microwave frequency domain characteristics of the interconnect system become increasingly important.

The traditional microwave frequency dependent ‘port’ measurements are scattering or S parameters, impedance or Z parameters, and transmission or T and ABCD parameters.

IFS Pro simulates all these parameters quickly and accurately prior to prototyping.

IFS Pro uses novel technology for modelling high-speed frequency-dependent losses in transmission line systems through the use of a unique lossy Spice network model generator and simulator.

This makes Interactive Products the first signal integrity tool company to produce a generic Spice model that can be run in any Spice platform that accurately models frequency-dependent losses (traditional frequency-dependent models account for a single frequency only).

This adds to the existing boundary element platform, which automatically generates an extensive electromagnetic report for any arbitrary geometry and augments the various Spice models created.

IFS Pro produces numerous Spice models ranging from lossless/lossy ladder to lossless/lossy modal, for both time domain and frequency domain analysis.

Time-domain plots include: voltage (including Vin,Vout, and crosstalk); and impedance probes (including single-ended and differential).

Frequency-domain plots include S-parameter, VSWR and eye pattern.
