Hi, my name is itay.I have a weird problem with the DSPBA: When I open the demo_AD9578 it compiles and run perfectly. I actually copy the same filter to my own model and I also make sure that all of the inputs are the same format. input is sfix(16)_En(15), coefs are the same, there are 17 symmetrical coefs (exactly the same as the demo), valid is boolean, ch is uint8, FPGA is stratix IV. When I run my model it doesn't compile and gives me the next error: "Found a non-synthesizable block in the synthesizable block" and points to the Single_Rate_Fir. What can be wrong? I am a bit frustrated about it, cause i am working on it for several days. thanks ahead, Itay.
