Analog Behavioral Modeling With The Verilog-A Language offers the IC dressmaker with an creation to the methodologies and makes use of of analog behavioral modeling with the Verilog-A language. In doing so, an outline of Verilog-A language constructs in addition to functions utilizing the language are provided. furthermore, the publication is followed by way of the Verilog-A Explorer IDE (Integrated improvement Environment), a constrained potential Verilog-A more advantageous SPICE simulator for additional studying and experimentation with the Verilog-A language. This e-book assumes a uncomplicated point of figuring out of using SPICE-based analog simulation and the Verilog HDL language, even if any programming language historical past and a bit decision may still suffice.
From the Foreword:
`Verilog-A is a brand new layout language (HDL) for analog circuit and platforms layout. because the mid-eighties, Verilog HDL has been used commonly within the layout and verification of electronic structures. notwithstanding, there were no analogous high-level languages to be had for analog and mixed-signal circuits and structures.
Verilog-A offers a brand new size of layout and simulation strength for analog digital platforms. formerly, analog simulation has been established upon the SPICE circuit simulator or a few spinoff of it. electronic simulation is essentially played with a description language equivalent to Verilog, that's well known because it is simple to profit and use. Making Verilog extra priceless is the truth that numerous instruments exist within the that supplement and expand Verilog's features ...
Behavioral Modeling With the Verilog-A Language presents an excellent creation and origin for college students and working towards engineers with curiosity in knowing this new point of simulation expertise. This e-book includes a number of examples that improve the textual content fabric and supply a priceless studying instrument for the reader. The textual content and the simulation application integrated can be utilized for person learn or in a school room surroundings ...'

Extra info for Analog Behavioral Modeling with the Verilog-A Language
The module defines the external ports or signals to which the module can connect as a component in the system. In this example, these signals are the indicated by the identifiers dout and din. 1, the connection points dout and din are defined as inout or bidirectional), as well as the type of the analog signals (electrical). The other facet of the interface declarations are parameter definitions which allow the characterization of the behavior of the component when it is used within a design. 0e6.
The assignment of the parameters and connections of child modules is done via parameter and port association. The Verilog-A language allows parameters to be assigned and ports to be connected by position or name. 2 Verilog-A definition of the modem system in Figure 2-1. carrier_freq(fc)) demod(dout, cout, clk) ; 1. Verilog-A language extends the Verilog HDL specification for structural definition via the addition of named association for parameters. This is discussed in more detail in the following chapters.
This is accomplished via the strict enforcement of conservation laws that the Verilog-A language semantics defined for the simulation of analog systems. 4. 0); Analog System Description and Simulation 17 Analog System Description and Simulation where $vt ()1 is a Verilog-A system task that returns the thermal voltage. Time-differential constructs as in the capacitor: can be expressed in the Verilog-A language as, I(n1,n2) <+ ddt(C*V(n1, n2)); where ddt() performs time-differentiation of its argument.
