Dalam projek ini, pengaturcaraan pemprograman untuk Alat Pembolehubah Voltan Analog (AVMC) dijanakan. AVMC digunakan untuk mengubah voltan, menggantikan chip ADM1066, disebabkan oleh kelenturan dan ketepatan alat tersebut. Pengaturcaraan voltan ditulis dengan menggunakan bahasa bash kerana bahasa tersebut sesuai digunakan untuk kerja pengautomasian. Pengaturcaraan tersebut memerlukan Sistem Pengujian Sistem Pengendalian (SVOS) di mana pengguna boleh menggubah voltan dengan hanya menaip kata kunci. Untuk mengesahkan kesahihan pengaturcaraan voltan, ia diuji ke atas tujuh papan Pinetrail dan lima papan Tigerhill. Setiap kali pengaturcara diaktifkan, voltan keluaran diukur dengan menggunakan multimeter digital dan ukuran tersebut dibandingkan dengan ukuran sebenar. Pengubahan voltan dijalankan ke atas setiap papan yang sedia ada dan ia menunjukkan pengaturcara voltan yang dijanakan berkesan. Dengan kata lain, pengaturcaraan voltan berjaya dijanakan dan digunakan untuk menjalankan ujian-ujian di Intel. _________________________________________________________________________________________ In this project, voltage automation scripts for Analog Voltage Margining Card (AVMC) are being developed. The AVMC card is a card used to support analog validation of a target test system. It supports margining of target voltage supplies through voltage and simulated current controls. AVMC is used to replace ADM1066 chip for the voltage margining due to its accuracy and flexibility. Voltage automation scripts are written using bash language because it is suited for automation tasks. For the scripts to work, an operating system called System Validation Operating System (SVOS) such that user can margin the voltage by entering a single command. The voltage margining scripts generated is being tested on two types of Intel board which are Pinetrail and Tigerhill. Seven Pinetrail and five Tigerhill boards are used for testing the voltage margining scripts. When running a script on a board, the output voltage on the board is being measured using a digital multimeter. The measurement is then compared to the actual or desired value of the user. Voltage margining had been carried out to each available board and it shows that the scripts work. Hence, the voltage margining scripts for AVMC had been successfully developed and is currently used for running test purposes in Intel.
