10. What our users say:
I am using Vissim 7.0 almost every day. I am very pleased with the functionality and new blocks that have been added with for the F280x controller from TI. I think that you are now achieving your statement (from the TI site) that VisSim ECD is capable of creating a complete control algorithm for the F280x directly from the VisSim environment.
As a developer of high and very-high power digitally-controlled power supplies, I don't have the time to get too much into the nitty gritty of the DSP and find the VisSim environment ideal for me. I would like to thank you for your support at VisSim and the continuing development of your software
