SystemVerilog has its own assertion specification language, similar to Property Specification Language. The subset of SystemVerilog language constructs that serves assertion is commonly called SystemVerilog Assertion or SVA. [6] SystemVerilog assertions are built from sequences and properties. Properties are a superset of sequences; any ...
The best way to achieve high confidence is to leverage the pre-silicon verification work — which can comprise as much as 30% of the overall cost of the implementation — and use that knowledge in the post-silicon system. Today, much of this work is done manually, which partially explains the high costs associated with system validation.
The original Verilog simulator, Gateway Design's Verilog-XL was the first (and only, for a time) Verilog simulator to be qualified for ASIC (validation) sign-off. After its acquisition by Cadence Design Systems, Verilog-XL changed very little over the years, retaining an interpreted language engine, and freezing language-support at Verilog-1995.
[citation needed] The properties to be verified are often described in temporal logics, such as linear temporal logic (LTL), Property Specification Language (PSL), SystemVerilog Assertions (SVA), [4] or computational tree logic (CTL). The great advantage of model checking is that it is often fully automatic; its primary disadvantage is that it ...
System Verilog is the first major HDL to offer object orientation and garbage collection. Using the proper subset of hardware description language, a program called a synthesizer, or logic synthesis tool , can infer hardware logic operations from the language statements and produce an equivalent netlist of generic hardware primitives [ jargon ...
A system design flow requires comparison between a transaction level model (TLM), e.g., written in SystemC and its corresponding RTL specification. Such a check is becoming of increasing interest in a system-on-a-chip (SoC) design environment.
Property Specification Language can be used with multiple electronic system design languages (HDLs) such as: VHDL (IEEE 1076) Verilog (IEEE 1364) SystemVerilog (IEEE 1800) SystemC (IEEE 1666) by Open SystemC Initiative (OSCI). When PSL is used in conjunction with one of the above HDLs, its Boolean layer uses the operators of the respective HDL.
Verilog was later submitted to IEEE and became IEEE Standard 1364-1995, commonly referred to as Verilog-95. In the same time frame Cadence initiated the creation of Verilog-A to put standards support behind its analog simulator Spectre. Verilog-A was never intended to be a standalone language and is a subset of Verilog-AMS which encompassed ...
