LogiCORE Sine-Cosine Look-Up Table (Sin Cos LUT) v2.1 - After installing D_IP2, I cannot select the Sine-Cosine Look-UP Table for generation (4000 and Spartan families).
After installing the D_IP2 update, I cannot see the Sine-Cosine Look-UP Table v_1.0 for generation. (NOTE: v2.1 is for Virtex and Spartan-II families only.)

For the CORE Generator GUI:
- Go to Project -> Update Cores -> Custom. - Navigate down to Math Functions -> Sine-Cosine LUT folder. - Delect Sine-Cosine Look-UP Table v1.0. - Click on "OK."
If you have "project option" set to XC4000, you should now be able to select v1.0 of Sine-Cosine LUT.
