SVA Properties IV : Until Property
A property is called “until property” if it uses one of the below until operators. until s_until until_with s_until_with Until properties are categorized as Overlapped & Non-overlapped and Strong &… Read more »

By using control statements, you can decide the order in which statements are executed. Conditional statements If-else case Loops forever repeat while for if-else Conditional statements are used to decide… Read more »
The implication construct (|->) allows a us to monitor sequences based on satisfying some criteria, i.e. for a sequence to occur, a preceding sequence must have occurred. The implication consists… Read more »
Operators are single-, double-, or triple-character sequences and are used in expressions.Following operators are available in Verilog HDL. Please note that not all operators are synthesizable. {} {{}} Concatenation +… Read more »
What is meant by lint? It was the name originally given to a program that flagged suspicious and non-portable constructs in software programs. Later this was extended to hardware languages… Read more »
Clock gating is a common technique for reducing clock power by shutting off the clock to modules by a clock enable signal.Clock gating functionally requires only an AND or OR… Read more »
SDF file is how you represent your circuit delays. We have earlier seen SPEF format which is the circuit’s RC representation. SDF now has the delay numbers derived from these… Read more »
By default, we expect every timing path to meet setup time in a single clock cycle. However, we can also specify that some data is captured only after a specified… Read more »
It is easy to get confused with the definitions of setup and hold violations. We are used to the definitions of setup and hold times for a single flipflop. The… Read more »
Sequence Properties Properties which contain sequence definitions are called sequence properties.Sequence properties are of three types. weak(sequence_expr) If there is no finite prefix that witnesses inability to match the sequence_expr,… Read more »
