Abstract
Techniques for configuring a test system that enable simple specification of a degree of concurrency in testing separate functional portions of a semiconductor device. For a test flow with multiple sub-flows, the pins accessed in connection with each sub-flow may define a flow domain. Site regions, each associated with a flow domain, may be defined. Tester sites may be associated with each of these flow domain specific site regions and independently operating resources may be assigned to these tester sites. A second portion of the defined site regions may be associated with tester sites, but resources assigned to these site regions may be accessed from multiple flow domains. Test blocks, even if not developed for concurrent execution, may be executed concurrently using resources in the flow domain specific site regions. Flexibility is provided to share resources through the use of the second portion of the site regions.
