This tutorial explores the design and co-design of embedded systems, specifically focusing on combinational and synchronous sequential logic in SystemC. It covers topics such as synthesis issues, if and switch statements, loops, and other constructs. The tutorial also delves into the description and synthesis of synchronous logic and provides practical examples.

Design & Co-design of Embedded Systems Combinational Logic (2) and Synchronous Sequential Logic in SystemC Maziar Goudarzi
Today Program • Rest of Synthesis Issues on Combinational Logic • Modeling and Synthesizing Synchronous Sequential Logic in SystemC Design & Co-design of Embedded Systems
Combinational Logic:If Statement • NOTE: • The target output must be assigned in all branches of the if statement. Why? Design & Co-design of Embedded Systems
Switch Statement • Same “if statement” rule applies also for “switch statement” Design & Co-design of Embedded Systems
Loops • (Normally) the only supported loop • For loop with compile-time determinable iterations Design & Co-design of Embedded Systems
Other Constructs and Notes • Methods • Structures • Multiple Processes and Delta Delay Design & Co-design of Embedded Systems
Synchronous Sequential Logic • Logic whose outputs depend: • not only on the current values of inputs • but also on their values in previous times • works synchronous to a clock edge Outputs Combinational Logic in1 in2 Memory Element in3 Design & Co-design of Embedded Systems
Synchronous Sequential Logic (cont’d) • Look at the handout • Chapter 6 of “A SystemC Primer” book Design & Co-design of Embedded Systems
Today Summary • How to describe combinational logic • For simulation • For synthesis • Synthesis semantics of various C++ constructs • How to describe synchronous logic • Mainly we discussed synthesis Design & Co-design of Embedded Systems
Assignments • Assignment 3: • Is put on the course web-page • Exercises of Chapter 4 of “SystemC Primer” book • Synthesize your models using the available tool • Due date: • Tuesday, Aban 24th Design & Co-design of Embedded Systems
Other Notes • Project Progress Report 1 • Today is the deadline • 2-3 pages, covering • List of your collected material • Summary of what you’ve done + demo of the C++ app. • Your plan for next phases and role of each person Design & Co-design of Embedded Systems
