Abstract
The present invention provides for a statistics Cyclic Redundancy Check (CRC) ) wherein the statistics CRC ( ) is representative of the values contained within a statistics RAM ( ). The statistics CRC ( ) is then used to reduce test vectors by allowing the validity of the statistics to be determined by reading this signature instead of reading all the individual statistics. The signature is regenerated for each complete pass of the statistics, and the contents of this register are only updated when the pass is complete.
