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
