// Testing Objectives:
|
|
// * inst can only be used in entities
|
|
// * inst must always refer to a valid proc or entity (match symbol name, input and output operands)
|
|
// * syntax: no inputs and outputs, one input zero outputs, zero inputs one output, multiple inputs and outputs
|
|
// * check that number of inputs and number of outputs are verified separately
