Flow / Reporting Improvements (QCD)
These enhancements make QCD faster and easier to use, including:
- Storage control - vastly reduces the amount of data recorded for swept-parameter simulations, allowing them to run faster and use less disk space
- Crosstalk speedup - eliminates AMI processing for "non-reported" receivers in crosstalk simulations, allowing simulations to run faster
- Snapshot (intermediate results reporting) - lets users roll-up partial simulation results during long runs, to see how trends are progressing
- Automatic frequency settings - The simulation parameters Max Input Frequency, Max Output Frequency and S-Param Frequency Step can now all be set to "Auto", in which case the simulator picks the best settings based on the data being used
- Max eye height and offset reporting - A key, but often under-appreciated feature of AMI models is that they return both equalized waveform data *and* clock ticks, which allows eye height to be measured at the instant the sampling latch captures the signal (the only point at which the eye height actually matters). The location of the sampling clock is usually not at the highest point of the eye, and it's desirable to know what the maximum eye height is and how the clock should be shifted to get there - which QCD now reports.
- Default clocking mode switched from Normal to Clocked - It was more common for models to use Clocked mode for clocking rather than the historical default of Normal model (independent), so we changed the default. Note, this may affect eye reporting compared with previous releases.
