Section 17 Assertions 17.1 Introduction (informative) SystemVerilog adds features to specify assertions of a system. An assertion specifies a behavior of the system. Assertions are primarily used to validate the behavior of a design. In addition, Chapter 19 Recommended Coding Practices (Writing Device Drivers) Chapter 19 Recommended Coding Practices. This chapter describes how to write drivers that are robust. Drivers that are written in accordance with the guidelines discussed in this chapter: Are easier to debug.
