Lecture on timing checks and pulse controlsTopics: Relation to assertions, the twelve verilog timing checks, pulse filtering and delay pessimism.Summary: This will complete our study of timing issues in verilog, as well as of the allowed contents of a
specify
block. We start by discussing the relationships among timing checks, assertions, and system tasks. After introducing the time-stamp/time-check rationale, we present the 12 timing checks and their default arguments. After describing conditioned events and timing-check notifiers, we explain verilog simulator pulse handling, inertial delay, thePATHPULSE
task, and pessimism reduction in thespecify
block. -
Lab on timing checksWe exercise the timing checks and pulse-filtering features of
specify
blocks. -
Lab PostmortemWe entertain a Q&A session only, this time.
