Abstract:
1. A method for verifying a functionality of ones of a plurality of dies arranged in a stack of dies, the method comprising the steps of: (a) operatively connecting a first die of said plural dies to a test bench external to the stack of dies and to a first peripheral module external to the stack of dies; (b) verifying a functionality of said first die to thereby produce a first input/output (“IO”) trace in a first format, wherein said first format is a signal level format; (c) disconnecting said first die from said test bench; (d) translating said first IO trace in the first format to a first IO trace in a second format, wherein said second format is a transaction level format; (e) operatively connecting a second die of said plural dies to said test bench and to a second peripheral module; (f) applying said first IO trace in the second format to said test bench; and (g) verifying a functionality of said second die via said first IO trace in the second format by using said test bench.
