Help required with the FreqSweep example

Altera_Forum · ‎11-19-2010

I am trying to understand the working of simulink models on FPGA. I am following the HIL design example that is illustrated in the DSP builder handbook volume 2 (pg. 5-3)

I followed the whole procedure until scan jtag to find available cables and hardware devices in the chain. However, when I click the "scan jtag" I get the following error

C:\altera\10.0\quartus\dsp_builder\bin\jni_jtag.dll: Can't find dependent libraries

??? Java exception occurred:

java.lang.UnsatisfiedLinkError:

Could someone please help me with this. What am I missing here and how to get it. Does DSP builder require any special version of JAVA?

Thanks

check QUARTUS_ROOTDIR, and the MATLAB path variables to see if they all point to 10.0

Yes. They both point to 10.0. The same error appears. Please help..
