| CAUSE 1: | In a Block Configuration at the specified location in a VHDL Design File (.vhd), you specified the configuration for the specified block. However, you did not define the block in a Block Statement. You must define a block before you can specify a configuration for the block. |
| ACTION: | In the Block Configuration, use a block that you already defined in a Block Statement. Or, use a Block Statement to define the block that is in the Block Configuration. However, do not define a block with the name you used in the Block Configuration if you already used the name for a different construct. |
| CAUSE 2: | In a Component Configuration at the specified location in a VHDL Design File (.vhd), you specified the configuration for the specified component instance. However, you did not define the component instance in a Component Instantiation Statement. You must define a component instance before you can specify a configuration for the instance. |
| ACTION: | In the Component Configuration, use a component instance that you already defined in a Component Instantiation Statement. Or, use a Component Instantiation Statement to define the component instance that is in the Component Configuration. However, do not define a component with the name you used in the Component Configuration if you already used the name for a different construct. |
