CIC-filter core

Hi, Vadim!

Thank you for a project. I have few notes:

• parametrization is useful, but too difficult
• problems with simulation (ies 10.2, vcs 2010.6)

It would be good to simplify the functions of parametrization, replace system task $clog2 on own version.

Best regards, Konstantin Bragin

Hi, Konstantin.

parametrization is useful, but too difficult

Did you read Hogenauers paper? I have no idea how to simplify expressions. All these complex calculations are used to automatically assign registers width.

problems with simulation (ies 10.2, vcs 2010.6)

Poor SV support issue.

replace system task $clog2 on own version

OK, agreed.

Best regards, Vadim Kotelnikov

PS: Any patches are welcome!

Hi Vadim,

Can u provide me the C-file which you have used for simulation .

When i run the TCL script it is showing the error

Can't locate a C compiler for compilation of DPI export tasks/functions.

Hi Avinash.

You need to install (or configure path to?) C-compiler (GCC). It's part of Modelsim distribution which I use.

Can you also provide testbenches for comb,integrator and downsampler please!
