Course Outline

Day 1
Static Timing Analysis
▪ Introduction to Clocking and Static Timing Analysis (STA)
 Describes the basics of clock gating, static timing analysis, and
 setup and hold slack. {Lecture}
UltraFast Design Methodology Timing Closure
▪ Introduction to UltraFast Design Methodology Timing Closure
 Provides an overview of the various stages of the UltraFast
 Design Methodology for timing closure. {Lecture}
▪ Baselining
Demonstrates the performance baselining process, which is an iterative approach to incrementally constrain a design and meet timing. {Lecture, Lab}
Design Analysis and Optimization
▪ Setup and Hold Violation Analysis
Covers what setup and hold slack are and describes how to perform input/output setup and hold analysis. {Lecture}
▪ Reducing Logic Delay
Describes how to optimize regular fabric paths and paths with dedicated blocks and macro primitives. {Lecture}
▪ Reducing Net Delay
Reviews different techniques to reduce congestion and net delay.
{Lecture, Lab}

Day 2

Design Analysis and Optimization (Continue)
▪ Improving Clock Skew
Describes how to apply various techniques to improve clock
skew. {Lecture}
▪ Improving Clock Uncertainty
Reviews various flows for improving clock uncertainty, including using parallel BUFGCE_DIV clock buffers, changing MMCM or PLL settings, and limiting synchronous clock domain crossing
CDC) paths. {Lecture, Lab}
Clock Domain Crossing (CDC)
▪ Clock Domain Crossing (CDC) and Synchronization Circuits
Explains what clock domain crossings (CDC) are and the scenarios that require synchronization circuits. {Lecture, Lab}
Report QoR
▪ QoR Reports Overview
Describes what quality of result (QoR) is and how to analyze the
QoR reports generated by the Vivado IDE. {Lecture, Lab}
Design Runs
▪ Intelligent Design Runs (IDR)
Introduces Intelligent Design Runs (IDR), which are special types
of implementation runs that use a complex flow to attempt to close timing. {Lecture, Lab}
