Abstract

A computer-implemented method includes generating a plurality of test cases to test exploitation of speculative execution in a design of a computer processor, where the plurality of test cases include a first test case. Generating the first test case includes identifying a branch responsive to an attempted access to secure data and, responsive to the branch, marking each memory address of each memory access dependent on the attempted access to the secure data. The computer-implemented method further includes executing the first test case. Executing the first test case includes detecting an attempt to access a memory address that has been marked and, responsive to the attempt to access the memory address that has been marked, alerting of a security violation.
