System Maximizer v. 1.1.4 Release Notes

Version 1.1.4 adds the following bug fixes and improvements over version 1.1.3

Bug Fixes / Improvements

New Components
Adaptive LMS FIR Filter
This component uses the Least Mean Square Algorithm to adapt the coefficients of a FIR filter.
Leaky Adaptive LMS FIR Filter
This component is similar to the Adaptive LMS FIR Filter, but brings the convergence constant to an input port, and includes a leakage factor (between 0 and 1.0) for increased stability
added the following functions :
- round
- integer
- saturate
- dead zone zero
- dead zone non-zero
- hysteresis functions
- splitBits - splits bits apart
- mergeBits - combines bits together
updated freqPlot paper tape output with delimitter before phase

System Maximizer v. 1.1.3 Release Notes

Version 1.1.3 adds the following bug fixes and improvements over version 1.1.2

Bug Fixes / Improvements

New components
IIR Reg where the first feed-forward coefficient is exactly zero, resulting in a fully registered IIR component. This avoids possible combinatorial feedback loops.
gaussian provides a source of random data with a guassian (normal) distribution. Specify the mean and standard deviation.
signal stats is a new sink which calculates minimum, maximum, mean, variance, and standard deviation.
Added printing, and image export to the following components
- scope panel
- dual scope panel
- freq plot
- xy plot
- xy sel plot
- polar plot
- polar sel plot
added autoscaling to :
- xy plot
- xy sel plot
- polar plot
- polar sel plot
updated transcendental functions to include abs and sqrt. The transc_func element now allows for :
sin, cos, tan, sinc, asin, acos, atan, ln, log2, log10, exp, pow2, pow10, abs, sqrt
fixed display bug which showed incorrect min and max values for scopePanel and dualScopePanel
updated and fixed bugs in parameter entry dialogs
fixed bug with copy when nothing is selected

This version is recommended for all users of System Maximizer version 1.1.2

System Maximizer v. 1.1.2 Release Notes

Version 1.1.2 adds the following bug fixes and improvements over version 1.1.1

Bug Fixes / Improvements

Fixed bug with relative paths in non-hierarchical designs
Fixed bug where design rule errors and warnings did not appropriately appear
Fixed bug with application crash
fixed UI bug changing parameter values, where occasionally, the value got stuck
added new component IIR Registered

added installation utility

This version is recommended for all users of System Maximizer version 1.1.1

System Maximizer v. 1.1.1 Release Notes

Version 1.1.1 adds the following improvements and bug fixes over version 1.1.0

Improvements / Bug Fixes

Support for Multi-rate systems
New Display Plotting Functions

XYSelPlot - combines line + scatter plots - useful for constellation patterns
PolPlot - polar plotting
PolSelPlot - combines polar + scatter plots

Improvements To Existing Plotting Functions (timePlot, dualTimePlot, XYPlot, freqPlot)

timePlot and dualTimePlot show scale information on left and right axis instead of as a legend
all graphing displays show the hierarchy path in the title bar
all graphing displays retain window settings when re-run from a hierarchical design
paper tape automatically closes when plotting window closes

Added a new reference design - 16-QAM Modulator which demonstrates :
- hierarchy
- multi-rate features
- constellation plots
Enhanced group selection - drag+drop, and copy/paste capability

groups may now be dragged/dropped across different designs
groups may now be dragged/dropped into other programs (as images)
Select All menu selects all elements and wires in a design

Error messages now display the hierarchy path (for hierarchical designs)
Fixed simulator bug where the simulator hangs when running designs with hierarchical designs which are saved in different relative subdirectories

New Multi-rate support

All non-constant (dynamically changing) sources, and registered elements are provided a new parameter called skip_rate, which determines how quickly this output will change. For single-rate systems skip_rate should be set to 0. A skip_rate of 2 will cause the source to skip a simulation cycle. In essence, it will run twice as slow, and data will be held constant on the following cycle. A skip_rate of 3 will cause the source to run at one third speed, and hold data for an additional two cycles. A skip_rate of 1 has no effect.

To decimate data by and integer rate, simply set the skip rate. To interpolate data to a higher integer rate, set the skip rate of the slower components appropriately. The result will be the same as increasing the sample rate and applying a zero-order hold. If you desire to insert zeroes instead of holding the data constant, insert a mux element to cycle between zero and the data.

For fractional rate interpolation and decimation, use the least common multiple, and set the skip rates appropriately. For instance, for 3/4 rate decimation. Start from a base of 12, and set skip_rates of 3 and 4 as appropriate.
