Generating device for scan capture constraint and generating method thereof

A generating device for scan capture constraint, comprising:

• a memory element storing first function constraint information, clock information, a netlist, a wrapper cell report, a hard macro instance list, and test mode configuration information;
• and
• a controller coupled to the memory element and configured to:
• perform a clock mapping operation according to the clock information, the netlist, and the first function constraint information to generate a clock mapping report;
• perform a timing constraint generating operation according to the first function constraint information, the clock mapping report, and the wrapper cell report to generate scan timing constraint information;
• and
• perform an automatic test pattern generation constraint generating operation according to the scan timing constraint information, the hard macro instance list, and the test mode configuration information to generate automatic test pattern constraint information.
