Latest Update V1.40 (12th November 2010)
This update adds the non-inverting active loop filter.
To update from an earlier version download SimPLL_V1_patchToVer1_40.zip. Includes all previous updates.
Update Instructions: unzip to extract the files, follow the instructions in readme.txt
Update: V1.31 (28th March 2007) - features added
- You can now specify a single frequency PLL, just specify the same frequency for the Min and Max frequencies
- The Transient simulation for this case then does a power-on simulation from the 0V VCO frequency (Note it will show the starting frequency as 0Hz)
- The frequency fields now have an autoprecision feature whereby they remember the precision of the value entered, up to 7 digits
|Tabulated phase noise data does not work for reference oscillator library files||fixed in V1.1|
|Occasional convergence error in time domain simulation||fixed in V1.2|
|Functioning software starts displaying error:
"There is an error in the SimPLL installation. The program will have to
be reinstalled. Error Number N = 125, M = 0."
|fixed in V1.2|
|Added Reference phase noise plot
Program sometimes crashes when reference phase noise added - occurs when Warning 622 or 623 showing
|fixed in V1.3|
|Added fixed freq capability (see below)
Added autoprecision on freq inputs
|Added non-inverting active loop filter||V1.40|
