DesignWare VIP problem!

[wagewage]

I want to use DesignWare vip in ntb. Is that OK?

when I compile ntb with vcs7.1,errors occure:

..........line 101 : Error: unsupported Vera construct 'vera_shell_param' encountered
}
" ", line 0 : Error: unsupported Vera construct 'attribute decl' encountered
}

What does that mean?How can I solve this problem?
Anyone who knows that!

hi wagewage ,
let me know about how to use DW cosine and Sine function?
how its works?
if u dont wanna use that function. how can i write my won code for cosine and sine function in combinational.
sorry i dont know to answer ur questions.

thanks in advance

You can either use a lookup table or use CORDIC algorithm for implementing SIn/Cosine generator. for using DW sine/cosine checkout the datasheet of the component from sold.

whizkid
i dont wanna implement in both ways (cordic or lookup table). i wanna implement in combinational logic , how synopsys design cos and design function.
sin x = 1 + x3/3! +x5 /5 ! ........
can u please give me some idea?

HI wagewage,

You must setup the VERA environment. Synopsys VIP need use VERA to generate all test vectors.
And check your license.

Good luck
