A computer system, computer readable storage medium, and computer-implemented method for generating a test program for a device-under-test (DUT). The method includes transmitting a plurality of uncompiled snippets and a plurality of uncompiled micro-functions into a compiler. The method also includes selecting, randomly, a portion of uncompiled micro-functions from the plurality of uncompiled micro-functions. The method further includes compiling the uncompiled snippets and the portion of uncompiled micro-functions, thereby generating a plurality of compiled snippets and a compiled portion of micro-functions. The method also includes interweaving, randomly, the compiled portion of micro-functions with the plurality of compiled snippets, thereby at least partially generating a test program for the DUT. The method further includes executing one or more post-silicon validation tests for the DUT with the test program.

A method for performing an address translation context switch includes initializing a computer processor to a first context by storing information identifying the first context in a control register of the computer processor. The first context specifies a mapping of virtual addresses of instructions to physical memory addresses in a first memory area. Information identifying a second context is stored in a memory address translation independent storage, where the second context specifies mapping of virtual addresses of instructions to physical memory addresses in a second memory area. The information identifying the second context is written to the control register of the computer processor.
