Why does the OSD fail to generate if the Bits Per Pixel Color Depth is set to 2? 

The following error occurs:

ERROR:sim - XST failed for v_osd_v3_0_R2p1. ERROR:HDLCompiler:1401 - "C:\Projects\Rotel\Design\Coregen_VideoOSD\VOSD_3p0\VOSD_3p0_R2p1\tmp\_cg\_bbx\v_osd_v3_0\osd_rt_gpu2.vhd" Line 819: Signal text_addr_comb[8] in unit ERROR:sim - Error found during generation.

解决方案

This is a known issue in the On Screen Display v3.0 that will be fixed in the next release.

You can work around this problem by setting the Bits Per Pixel Color Depth to 1.
