Abstract

A technique is described whereby a single testing device is used to functionally test boards and cards for the IBM Personal Computer (PC). The Functional Acceptance Card Tester (FACT) eliminates the need to have a variety of different testers and testing devices. It has the ability to test many different types of circuit cards, thereby providing a high degree of reliability involving correlation, accuracy and repeatability. The FACT, as shown in the block diagram, is controlled by the supervisory control processor (SCP) 10 which is connected to the diagnostic processor 11 through interface PC link 12. The SCP controls the following routines: 1. Test setup and origination of test execution. 2. All operator and error messages. 3. Yield data management control. 4. RS 232 communication control. 5.

Functional Acceptance Card Tester

A technique is described whereby a single testing device is used to functionally test boards and cards for the IBM Personal Computer (PC). The Functional Acceptance Card Tester (FACT) eliminates the need to have a variety of different testers and testing devices. It has the ability to test many different types of circuit cards, thereby providing a high degree of reliability involving correlation, accuracy and repeatability. The FACT, as shown in the block diagram, is controlled by the supervisory control processor (SCP) 10 which is connected to the diagnostic processor 11 through interface PC link 12. The SCP controls the following routines: 1. Test setup and origination of test execution. 2. All operator and error messages. 3. Yield data management control. 4. RS 232 communication control. 5. All file and data handling. 6. Manual debug control software. The diagnostic control processor 11 executes the option unit under test (UUT) 13 software as directed by the SCP and controls the I/O simulators 14. The I/O simulators 14 provide two basic types of tests: 1. Diskette drive simulators 14 simulate four drives using one floppy disk drive and exercise all the functions of the disk controller. 2. Versatile I/O simulator - used to test the simpler PC option cards. The PC link 12 provides the communication link between the SCP and the diagnostic control processor. When testing CPU type cards 15, the diagnostic control processor (DCP) 11...
