Certain Changes Made in the Clipper II Parameter Editor are Ignored

Critical Issue

Description

When you select rectangle mode as the clipping method, the mode is not propagated into HDL.

The clipping rectangle height, width, and offset parameters are restricted to HD resolutions. This issue affects version 15.0 of the Clipper II IP core.

Resolution

To work around this issue, edit the TCL files.

To propagate the rectangle mode, edit /../ip/altera/vip/ip_library/full_ip/cl_clipper/alt_vip_cl_clp_hw.tcl lines 138 and 146 to read "set_parameter_property RECTANGLE_WIDTH HDL_PARAMETER true" and "set_parameter_property RECTANGLE_HEIGHT HDL_PARAMETER true".

To remove the restrictions for the height, width, and offset parameters, edit /../ip/altera/vip/ip_library/full_ip/cl_clipper/alt_vip_cl_clp_hw.tcl lines 106, 113, 121, 128, 136 and 144, replacing "1920" with "4096" and "1080" with "2160".

This issue will be fixed in a future version of the Clipper II IP core.
