How can I set initial values for Floating Point Megafunctions??

Dear DvM

Thank you for your reply.

My reading of the Floating-Point Megafunctions users guide however is, that the IP isn't prepared to produce defined output during startup.

I also read the users guide and got the same answer as you mentioned.

It's pretty weird that signal initialization cannot be done.

Anyway

In this case, you may want to add a multiplexer to the design that feeds zero to the IIR loop for some clock cycles to reset the filter.

I tried to realize this but got new problem.

Multiplexer needs "switch" signal to choose which input signal is to be read out.

Since undefined signals can not be read as "undefined," I think it's impossible to produce the switch signal nor asynchronous clear signal.

Hence I cannot reset my filter...

Please help me out...
