Analog verification is a methodology for performing functional verification on analog, mixed-signal and RF integrated circuits and systems on chip. [1] Discussion of analog verification began in 2005 when it started to become recognized that the analog portion of large mixed-signal chips had become so complex that a significant and ever-increasing number of these chips were being designed with ...
In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. The most commonly used linear function of single bits is exclusive-or (XOR). Thus, an LFSR is most often a shift register whose input bit is driven by the XOR of some bits of the overall shift register value.
In computing, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, called the modulus of the operation.. Given two positive numbers a and n, a modulo n (often abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor.
Verilog-2001 is a significant upgrade from Verilog-95. First, it adds explicit support for (2's complement) signed nets and variables. Previously, code authors had to perform signed operations using awkward bit-level manipulations (for example, the carry-out bit of a simple 8-bit addition required an explicit description of the Boolean algebra ...
A test bench or testing workbench is an environment used to verify the correctness or soundness of a design or model.. The term has its roots [citation needed] in the testing of electronic devices, where an engineer would sit at a lab bench with tools for measurement and manipulation, such as oscilloscopes, multimeters, soldering irons, wire cutters, and so on, and manually verify the ...
Main features of e are: Random and constrained random stimulus generation. Functional coverage metric definition and collection. Temporal language that can be used for writing assertions. Aspect-oriented programming language with reflection capability. Language is DUT-neutral in that you can use a single e testbench to verify a SystemC/C++ ...
A binary counter can represent 2 N states, where N is the number of bits in the code, whereas a straight ring counter can represent only N states and a Johnson counter can represent only 2N states. This may be an important consideration in hardware implementations where registers are more expensive than combinational logic.
Intelligent Verification, including intelligent testbench automation, is a form of functional verification of electronic hardware designs used to verify that a design conforms to specification before device fabrication. Intelligent verification uses information derived from the design and specification (s) to expose bugs in and between hardware ...
