Claim 11:
12. A computing system peripheral device for connecting to a bus of the computing system, the peripheral device comprising:
a bus interface configured to communicate data with one or more separate devices via the bus, wherein the one or more separate devices include error correcting code (ECC) circuitry configured to generate ECC data and use the ECC data to detect data errors in data communicated via the bus;
logic circuitry configured to initiate sending a write request to the one or more separate devices via the bus; and
a bus ECC circuitry checker configured to:
force an error on the bus and compare a response of the ECC circuitry of the one or more separate devices to the forced bus error to an expected response of the ECC circuitry;
generate an alert when the comparing indicates an error in the ECC circuitry; and
force an error in one or both of write data and a write address included in the write request and compare a returned status of the write request to an expected returned status.
