EMPOWER memory usage was higher than expected in lossy case. |
Uses 2-3 times expected memory |
EMPOWER |
Emport properties box said Length instead of Height |
EMPOWER properties box, comment at bottom specifies "width and/or length", width and height are given |
Equations |

If the FREQ variable is used without a linear simulation, a GPF resulted. |

Various Post-Processing Equations gave zero results. |
The following operation doesn't work:
=.DB[S21]@1400-.DB[S21]@1600

Error Messages |
Interdigital Cap: Misleading error when substrate definition is iIncomplete |
User is getting error when he tries to use MIDCAP model: Invalid use of operator (*) at (Unknown part/Line). Error was being caused by a missing parameter in substrate definition. Error is misleading. Version 7 didn't return any errors. |
Export |
DXF layer names cannot contain spaces. |
The extra space in the layer name (e.g: TOP METAL) causes error messages in some CAD packages used for manufacturing. |
FILTER |
The Save Dialog box doesn't work as expected |
FILTER is now integrated, no longer applies. |
FILTER |
Some hotkeys were duplicated |
FILTER is now integrated, no longer applies. Bandstop and Shunt C Coupled (Allpole BandPass) both use S as the hotkey. |
FILTER |
Show error when parts are negative |
There should be some sort of indicator (an ERROR?) when negative values show up in a filter. Now, parts show purple. |
Graphs |
Smith Chart can crash if zoomed in to ridiculous range |
|
Graphs |
3D Graph can crash if no data defined. |
|
Graphs |
Graphing vertical axis log scale should be disabled. |
Advanced Properties/Y axis/Log scale is disabled. |
Graphs |
Restore Default Graph Settings on Load does not work |
This option was ignored. |
Graphs |
Graphs need better zooming |
Now, toolbar, keyboard, and mouse wheel are supported. |
Graphs |
Add File/Export for Data Tables |
Automatic export of text file from tabular output. |
HARBEC |
DC analysis gives zero results in some cases |
When tuning, DC would sometimes give zero answers. |
HARBEC |
HB with many tones may take too long to initialize spectrum calculation |
HB analysis, if there are very large number of tones (more 6) and large orders of harmonics of each tone. |
HARBEC |
Changing frequency to an undefined variable crashes the software |
Change schematic frequency from 1000 to fo, without defining fo, crashes software. |
HARBEC |
Nonlinear Multitone sources DC use more nodes than necessary |
If a circuit uses a n-tone source with DC<>0, then it is translated to n Spice SIN sources with the same DC value each, as result the DC value becames equal to n*DC. |
HARBEC |
Want to control simulation temperature & view noise in HARBEC |
Would like to see the effect on noise and gain as temperature is varied. |
HARBEC |
In CURTICE3 model, specifying CRF but not RC gives inconsistent results |
Specifying an extra output capacitance but not resistance gives different results in Harbec vs. Linearized simulation. |
HARBEC |
Nonlinear FET models STATZ_N noise parameters are not specified correctly |
Instead, the model is interpreting FNC as flicker coefficient, typically a very small number like 12E-10. In other words, the model has put the wrong label on the variable it is asking the user for, causing the user to enter a number in the millions when in fact it should be getting a number in the picos or nanos. |
HARBEC |
Long Filenames with spaces fail in Spice link |
For example "C:\Zipped Files\x.lib" fails. |
Import |
Importing version 4/5/6 CKT file with multiple substrates fails |
|
LAYOUT |
Feature Request: Add Step and Repeat to Layout |
|
LAYOUT |
Feature: Ability to Output GDSII Files |
Support GDSII as layout output. This format is very popular for high-frequency work (on ceramic substrates) and for IC/semiconductor design. |
Linear Simulation |
W1=W2 in microstrip step, model creates null data |
If W1=W2 in a step, the model should "disappear". Instead, the data goes invalid. |
Linear Simulation |
SBN model does not include reference plane shift |
Stripline Bend Accuracy is now improved. |
M/FILTER |
Zero slide factor fails |
A slide factor of zero in edge-coupled microstrip causes problems. |
M/FILTER |
M/FILTER: Electrical Variables sometimes displayed Physical Values |
The Utilities|View Electrical Variables will often display the odd mode impedance where the coupling coefficient should be displayed. That is, K1=18.1850 is displayed instead of K1=0.00047. |
M/FILTER |
Write CKT File and escape causes loop |
Now integrated into GENESYS, not an issue. |
M/FILTER |
M/Filter crashes when defaults are "bad" |
Fixed various out-of-range problems. |
Miscellaneous |
First frequency problem when FREQ is used |
When FREQ is called the first frequency is 0 Hz even if the real sweep starts at 100 MHz. Dividing by FREQ then causes an overflow and other problems. |
Miscellaneous |
Toolbars need to stay in docked position |
Toolbars need to stay in docked position (stay where user put them). |
Miscellaneous |
Dialog boxes need HELP button |
Dlg boxes need HELP button, not just F1 key for help. |
Miscellaneous |
Double-clicking in explorer to open file shows 8.3 abbreviated name |
Double-clicking a WSP file in explorer to run GENESYS and load the file will show the filename and pathname with a Tilde. |
Miscellaneous |
Add option to dump table data to a file automatically. |
Add a line to the table properties dialog to specify a filename where the data is automatically output in text format. |
Miscellaneous |
Variable Viewer cuts off variables with long names |
Put a long name, "abcdefghijlkmnopqrs = 3.34134134" in the equations. Add a variable viewer output. The column won't be wide enough to see the result. |
Miscellaneous |
GENESYS changes file date on closure even if no changes |
If you open a wsp file and make no changes, then just close it, the file date gets updated on the close. |
Models |
MIDCAP model needs to be improved |
Interdigital Capacitor |
Models |
Stripline SLIO model does not work in LAYOUT |
Offset Stripline: Variables for this model are (W) width, (A) offset from substrate center and (L) length. The problem is that Layout takes the (A) number and interprets it as Length.
|
Models |
AIRIND AIRIND1 model unit of measurements are always mm. |
Inductor model AIRIND1 (under lumped menu) appears to allow the user to switch in what units its variables are given. However, the model appears to continue assuming that the input numbers are in mm no matter what unit choice the user gives. |
Models |
Negation Block symbol should be improved |
Negation symbol is not the right size. We should have some sort of port direction on it. It is very easy to accidentally reverse the negation block. |
Models |
MINV and MSUS don't work in LAYOUT. |
Layout uses the wrong parameter for line length for inverted/suspended substrate lines. |
Models |
SPIND model too small in LAYOUT. |
Spiral Inductor. |
Models |
Zero values cause models to give math errors |
Zero values cause some models to blow up due to zeros in denominator. |
Optimization |
Want to be able to disable sets of optimization targets. |
Can now right-click on opt/yield target in tree and deactivate. |
SCHEMAX |
Part Dialog is not remembering "show text" checkbox for text objects |
Double clicking the text in Schemax will enable all text lines even if they have been previously hidden. |
SCHEMAX |
Make schematic curve elements look like curve |
Make the curve elements in schemax look like a curve, it now looks like a straight segment |
SCHEMAX |
SBCP model is inconsistent |
Stripline Broadside Coupled Lines. |
SCHEMAX |
Want an easy way to make schematics fit on the printed page |
Making a schematic fit on the printed page is cumbersome: you have to guess the right size for the parts. Would like an automatic "fit to sheet" operator. (Added Fit to Page and Center to Schematic Menu.) |
Statistics |
Monte carlo setup variables Up/Down% are reversed. |
|
Statistics |
Yield optimizer reverts to old values after completion. |
|
Synthesis |
Allow easy reset of synthesis to factory defaults. |
Added option on Create synthesis |
Synthesis |
FORMAT ERROR on entering numbers into Synthesis modules |
Open MATCH and create a simple MATCH circuit. Change the port impedances away from 50 Ohms by opening the box and hitting the delete key to delete the "50". On deleting the last character, an error message box comes up - annoying. |
Tuning |
The errors/warning window terminates tuning |
If you tune a parameter to a yellow condition, it terminates the tune because the error/warnings window grabs the focus. Added local error messages/orange parts to prevent this. |
