In … WebApr 22, 2015 · Functional coverage is used as aguide to direct the verification resources by identifying the tested and untested parts of thedesign. When properly used, functional coverage can serve as a formal specification of a testplan.

WebTo manipulate the coverage data and filter it binsof and intersect constructs are useful The binsof construct yields the bins of its expression The resulting bins can be further selected by including (or excluding) only the bins whose associated values intersect a desired set of values. binsof( x ) intersect { y } denotes the bins of coverage ...

WebJul 7, 2024 · This chapter explores SystemVerilog functional coverage in detail. It discusses methodology components, covergroups, coverpoint, and various types of “bins” including binsof, intersect, cross, transition, wildcard, ignore_bins, illegal_bins, etc. The chapter also discusses sample/strobe methods and ways to query coverage. http://www.asic-world.com/systemverilog/coverage20.html

Introduction: This chapter covers the entire “Functional Coverage” language. We will cover the following features in the upcoming sections. 1. covergroups and coverpoints for variables and expressions. 2. automatic as well as user-defined coverage bins. 3. “bins” for transition coverage.
WebFeb 25, 2024 · 2.coverpoint and bin. In order to calculate the coverage on a coverpoint, we first need to determine the number of possible values, which is also called domain. Coverage is the number of sampled values divided by the number of bins. For example, the domain of a 3-bit variable is 0:7. Normally, 8 bins will be automatically allocated.
