CS302 Digital Logic Design is a core foundational computer science and electrical engineering course in the Virtual University curriculum, engineered to equip undergraduate scholars with deep conceptual mastery of digital hardware architectures, binary arithmetic, and modern logic synthesis. Grounded in authoritative classical references including Digital Systems: Principles and Applications by Ronald J. Tocci and Digital Design by M. Morris Mano, the course provides a rigorous progression from foundational Boolean algebra to advanced sequential and programmable logic design. Students begin by mastering number systems, binary conversions, 1's and 2's complement arithmetic, signed integer representations, floating-point formats, and error-detecting codes like BCD, Gray code, and parity bits. The curriculum proceeds to fundamental logic gates, operational voltage parameters, fan-out, propagation delay, and Boolean function simplification utilizing Boolean theorems and multi-variable Karnaugh Maps (K-Maps) in SOP and POS forms. In combinational logic, learners design comparators, parity generators, ripple-carry adders, BCD adders, look-ahead carry units, and 16-bit Arithmetic Logic Units (ALUs), alongside multiplexers, demultiplexers, encoders, and decoders. The syllabus transitions to programmable logic devices, exploring PAL, PLA, and GAL16V8 architectures with ABEL hardware description language. In sequential logic, students analyze S-R latches, switch debouncing, D and J-K flip-flops, master-slave configurations, monostable/astable 555 timers, asynchronous ripple counters, and synchronous up/down decade counters. Advanced modules cover finite state machine (FSM) modeling, next-state tables, state assignment, shift registers, semiconductor memories (ROM, SRAM, DRAM, Flash, FIFO/LIFO), FPGA logic blocks, and analog-to-digital (ADC) / digital-to-analog (DAC) converters. Supported by verified VU course handouts, solved past examination papers by Moaaz and Waqar Siddhu, and chapter-wise solved practice MCQs, CS302 provides comprehensive preparation for university examinations and digital hardware engineering careers.
