What is SPICE Verilog?

What is SPICE Verilog?

The SPICE netlist format is often a complex way of describing a circuit topology. With Verilog-A rich C like syntax and clear growth path, Verilog-A is a suitable successor to a method of describing circuit topologies. The Verilog-A language is supported by both SmartSpice and Harmony.

What is electrical in Verilog-A?

The second line declares the pins as being electrical, meaning that the potential of each pin is a voltage and the flow into the pin is a current. Verilog-A defines the flow on the pin to be positive if the motion is into the component.

What is Hspice?

HSPICE is an analog circuit simulator (similar to Berkeley’s SPICE-3) capable of performing transient, steady state, and frequency domain analyses. HSPICE generally has better convergence than SPICE-3 and, because it is a commercial product (from Meta-Software), is better supported.

What is Verilog-A model?

Verilog-A is an industry standard modeling language for analog circuits. It is the continuous-time subset of Verilog-AMS.

What is the use of System Verilog?

SystemVerilog, standardized as IEEE 1800, is a hardware description and hardware verification language used to model, design, simulate, test and implement electronic systems.

What is always block in Verilog?

In Verilog, the always block is one of the procedural blocks. Statements inside an always block are executed sequentially. An always block always executes, unlike initial blocks that execute only once at the beginning of the simulation. The always block should have a sensitive list or a delay associated with it.

What is hspice model?

PrimeSim HSPICE is the industry’s ‘gold standard’ for accurate circuit simulation and offers foundries-certified MOS device models with state-of-the-art simulation and analysis algorithms. …

What is hspice used for?

Hspice is a device level circuit simulator. Hspice takes a spice file as input and produces output describing the requested simulation of the circuit. It can also produce output files to be used by the AWAVES post processor.

Is Verilog-a RTL?

RTL is an acronym for register transfer level. This implies that your Verilog code describes how data is transformed as it is passed from register to register. The transforming of the data is performed by the combinational logic that exists between the registers.

Is Verilog hard to learn?

Learning Verilog is not that hard if you have some programming background. Verilog and VHDL share more or less same market popularity, but I chose Verilog since it is easy to learn and its syntactical similarity to C language. Once you are comfortable with Verilog, it should be easy to learn VHDL as well.
