Abstract
Techniques are provided for design verification of a bit spreading memory. A methodology implementing the techniques according to an embodiment includes using a bit spreading geometry file to convert a logical address of the memory to a physical address. The geometry file defines a scheme by which bits of a data word stored at the logical address are spread over multiple RAMs. The method also includes writing data bits of a test data word to the physical address, causing a design simulator to simulate a read from the logical address, and comparing the result to the test data word for verification. The method further includes causing the design simulator to simulate a write of the test data word to the logical address, reading data bits from the physical address, arranging the bits into a retrieved data word, and comparing the test data word to the retrieved data word for verification.
