The procedure validates that the test limits used during the self-diagnostic are accurate. During operation, each pin driver is continuously monitored and calibrated by a special supervisory circuit. The selfdiagnostic test verifies correct operation of the pin drivers, power supply, CPU memory, and communications.Table 1 lists the frequency Microsemi(R) recommends for running the self-diagnostic test. Table 1: Recommended Self-Diagnostic Testing Frequency Frequency Type of Product Recommendation Once for every job Non RT/RH Required Prior to programming every device All RT/RH devices Required Note: Do not place any FPGA in the module during self-test. It is also necessary to validate the accuracy of the self-test. This validation insures the self-test provides accurate results. Table 2 lists the frequency Microsemi(R) recommends for running the calibration verification test. Microsemi performs calibration verification test before shipping every unit. Table 2: Calibration Verification Frequency Frequency Type of Product Recommendation Once every year All non RT/RH devices Required Once for every job All RT/RH devices Required The following materials are used: * Digital Voltmeter and required probes * Oscilloscope and required probes * 48-Pin Socket Module, PN SM48DB, or SM48D * Silicon Sculptor II or Silicon Sculptor 3 * The latest Silicon Sculptor Software is available here: www.microsemi.com/soc/download/program_debug/ss/files.aspx January 2013 Figure 1 shows an SM48DB and a digital voltmeter in front of a Silicon Sculptor programming module. The unit next to the programmer is an oscilloscope. Figure 1: Materials Needed for Verification of Calibration The SM48D and SM48DB both have two rows of pins. Figure 2 shows how to mark the SM48D/SM48DB module pin numbers and identify the pin numbers. Pin 1 is mentioned in the top left and marked on the chassis. The pin starts from the top left to pin 24 on the bottom left, then pin 25 on the bottom right to the pin 48 on the top right. Pin 48 Pin 24 Pin 25 Figure 2: Mark the SM48D/SM48DB Module Pin Numbers 4 Silicon Sculptor Verification of Calibration Work Instruction Verifying the Calibration This procedure can be implemented using Silicon Sculptor II or Silicon Sculptor 3 programming modules. Silicon Sculptor refers to either Silicon Sculptor II or Silicon Sculptor 3, depending on your programmer of choice. 1. Connect the Silicon Sculptor programmer to a parallel printer port on your PC. For Silicon Sculptor II, connect the programmer to a parallel printer on your PC. Connect one end of the cable to the programmer's connector and tighten the screws. Plug the other end of the cable into your parallel printer port. For Silicon Sculptor 3, connect the programmer to a USB port on your PC. Connect one end of the cable to the programmer's connector and tighten the screws. Plus the other end of the cable into the USB port. 2. Place the programming module on top of the Silicon Sculptor programmer. 3. Plug the Silicon Sculptor programmer AC power cord into a power socket. 4. Turn on the computer and programmer. Silicon Sculptor II is performing a power-on self-test when the Active LED is on. 5. Open Silicon Sculptor software v4.62.0. 6. Press Device to open the Select Device window as shown in Figure 3. Alternatively, the Diagnostics can be accessed from the Tools Menu by selecting Programmer Diagnostics. Figure 3: Select Device Dialog Box 7. Select Actel Diagnostics and press Select. Silicon Sculptor Verification of Calibration Work Instruction 5 8. Press Test. The Test window appears as shown in Figure 4. Figure 4: Test Window 9. Use the default selections: - Loop Mode: Single - Units to Test: Single - Memory Test: Off - Unit Number: 1 - Decimal 10. Press OK. The software detects the power supply calibration. If the software detects an incorrect calibration, it generates a Failure message: Testing current regulators: Coarse mode Icc regulation faulty or needs calibration (9.205mA should be 30mA). Silicon Sculptor automatically recalibrates the programmer. When the procedure is complete, Silicon Sculptor generates a Pass message. In the event of any failure, contact Microsemi SoC Tech Support along with the log file (C:\BP\DATALOG). The remainder of the procedure focuses on complete validation of the calibration. 6 Silicon Sculptor Verification of Calibration Work Instruction Validating the Calibration This section requires the use of an SM48DB or SM48D 48-pin socket module. 1. During the test, the Diagnostics Info window appears as shown in Figure 5. Figure 5: Diagnostics Info 2. Press Yes to check the settings with a voltmeter. The program runs a quick check on some of the functions. The Verify Voltage Calibration window appears as shown in Figure 6. Figure 6: Verify Voltage Calibration Window 3. Move this screen off to the side, so that you can view the tolerance levels. Use the voltmeter to view the readings. Record these levels on the verification sheet. 4. Place the red probe onto pin 1 and the black probe onto pin 3. Verify the reading is within the tolerance range and record readings. 5. Place the red probe onto pin 2 and the black probe onto pin 3. Verify the reading is within the tolerance range and record readings. If readings are not within the tolerance range, Silicon Sculptor needs to be marked as failed. Silicon Sculptor Verification of Calibration Work Instruction 7 6. Click OK. The Verify AC Calibration window appears (as shown in Figure 7. Figure 7: Verify AC Calibration Window The AC calibration window displays the tolerance for the pulse width. The pulse width needs to be viewed using the oscilloscope. 7. Place the probe onto pin 1 and the ground onto pin 3. Verify the pulse width is within tolerance range. Record readings. If reading is not within the tolerance range, Silicon Sculptor needs to be marked as failed. When disconnecting the probe and ground, disconnect the probe first. If the ground is disconnected first the test will read fail. 8. Click Close. The Silicon Sculptor software continues to test the unit and displays the results. The results include the serial number of the unit, and if it passed or failed. Document the results. The verification of calibration is complete. If the unit failed the verification of calibration, contact Microsemi Technical Support for instructions.If the unit passed the verification of calibration, the associated documentation needs to be replaced. 9. Fill out the Certificate of Conformance, and replace the old certificate. Calibration date is the date the test was completed. Calibration is due one year after the date tested. 10. Fill out the certificate sticker with the correct information, and place over the old sticker located on the Silicon Sculptor. 8 Silicon Sculptor Verification of Calibration Work Instruction List of Changes The following table lists critical changes that were made in the current version of the chapter.
