What’s HSPI

HSPI is a post processing tool for signal integrity (SI) and power integrity (PI) engineering. It has the capability of batch processing waveform data generated from hspice or other circuit simulators, as well as data from oscilloscope measurement, and creating comprehensive Excel report for SI and PI engineering. Besides report generation, HSPI also has powerful waveform plotting functions that can highlight issues such as edge glitch, excessive ringback, and etc in different colors. The eye diagram function can overlay multiple simulation waveforms in a signal plot. The DDR3 eye diagram function can mark eye opening with trapezoidal mask and overlay DQS/#DQS in the same plot. HSPI can greatly improve your productivity in SI and PI analysis.

The major features of HSPI include:
1. Display waveform with zoom, pan, and cursor.
2. Export waveform in text format or in hspice PWL sub-circuit format.
3. Digitize and visualize analog waveform in digital bits based threshold voltages, and highlight glitch and ringback for each data bit.
4. Measure signal quality such as ring back, noise margin, and etc.
5. Measure signal timing such as slew rate, flight time, setup/hold time, pulse width, duty cycle, and etc.
6. Visualize eye diagram and eye mask. Support overlay eye diagram from multiple files.
7. Measure noise and timing margin of eye diagram.
8. Measure signal jitter and flight time jitter.
9. Measure DDR3 signal quality and timing, including tangent slew, automatic derating, and etc.
10. Measure signal pull-in / push-out or setup / hold SSO due to power delivery noise.

What's new

Version 3.1 now adds:
1. Add extended mask mode in serial bus center. This new mask mode applies to some new interface spec such as V-by-1 for digital display panel. It also can accommodate some irregulator mask shape such as DDR trapezoidal mask under serial bus center.
2. Add “data valid extended” in DDR3 setup and hold time measurement. The new mode recycles the originally discarded shorter bits in bit split scenario (see manual) and provides more robust setup and hold time measurement.
3. Rewrite the serial bus report algorithm for non-automatic mask center setting for more accurate time margin measurement.
4. Add extended derating tables for DQ/DQS by extending each row to cover all the "not supported" cells (JESD79-3D page-204).
5. Save/Load all HSPI settings and lists in text based project file (*.hspi). So user can customize HSPI with text editor or scripts.
6. Quick eye (qEye) in the waveform plotting window for fast eye diagram plotting.
7. Pessimistic jitter in serial bus center. This captures uncertainty of the detector threshold with jitter.
