Incorrect Built-In Test Pattern Generator Background Color in Mixer II IP Core

The Mixer II IP core may display incorrect built-in test pattern background color.

To fix this problem, follow these steps:

1. Open the /../ip/altera/vip/ip_library/full_ip/cl_mixer/alt_vip_cl_mixer_hw.tcl file and edit these lines.

Edit lines 227-233:

set pattern [get_parameter_value PATTERN] if { [get_parameter_value COLOR_PLANES_ARE_IN_PARALLEL] == 1 } { set symbols_in_par [get_parameter_value NUMBER_OF_COLOR_PLANES] } else { set symbols_in_par 1 }

To:

set pattern [get_parameter_value PATTERN] set cspace_is_rgb [string compare [get_parameter_value COLOR_SPACE] "RGB"] set pattern_is_uniform [string compare [get_parameter_value PATTERN] "uniform"] if { [get_parameter_value COLOR_PLANES_ARE_IN_PARALLEL] == 1 } { set symbols_in_par [get_parameter_value NUMBER_OF_COLOR_PLANES] } else { set symbols_in_par 1 } if { == 0} { set use_background_as_border 1 } else { set use_background_as_border 0 }

Edit line 297:

set_instance_parameter_value tpg USE_BACKGROUND_AS_BORDER 0>

To:

set_instance_parameter_value tpg PATTERN set_instance_parameter_value tpg UNIFORM_VALUE_RY set_instance_parameter_value tpg UNIFORM_VALUE_GCB set_instance_parameter_value tpg UNIFORM_VALUE_RY set_instance_parameter_value tpg USE_BACKGROUND_AS_BORDER

2. Save the file in the same location.
3. Refresh Qsys and regenerate the system.

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