In programming, instantiation is the creation of a realinstanceor particular realization of an abstraction ortemplate, such as aclassofobjectsor a computerprocess. To instantiate is to create such an instance by
The Verilog for the AND gate looks like this: module my_and(inp1,inp2,rst); // define the module call input inp1, inp2; // define inputs and output output rst; assign rst = inp1 & inp2; // use the & (and) operator endmodule The logic takes the value at the two input ports...
For example, imagine you wanted to buy a preexisting IP from a vendor. Without UVM there is no standard to define the interoperability of the IP block or the features it shall include (scoreboard, agent, monitor, sequencer, etc). Much time will be spent integrating the block into your env...
In my previous post aboutSystemVerilog and Verilog X Optimism – You May Not Be Simulating What You Think, I discussed what is Verilog X optimism, and some coding styles that are prone to Verilog X optimism bugs. So how do you avoid potential bugs that Verilog X optimism can introduce? On...
The DVM source and load symbol dialogs have been updated to use the Power Supply dialog. This allows the ability to define measurements on the four internal probes (voltage, current, gain or magnitude, and phase) for each of the source and load types. ...
Before defining physical synthesis, it is useful to define logic synthesis. Pioneered by Synopsys, logic synthesis takes as an input a description of a circuit expressed in a high-level language such as Verilog or VHDL. Other inputs include timing constraints for the design as well as the spec...
In fact, a wide range of tools -- including Perforce IPLM (formerly Helix IPLM) -- now exist to fulfill this in-demand function. But what is semiconductor IP and IP core (or intellectual property core)? Below, we define what is IP core -- including soft IP and hard IP. We also...
This paper proposes a standard synthesis subset for SystemVerilog. The paper reflects discussions with several EDA companies, in order to accurately define a common synthesis subset that is portable across today's commercial synthesis compilers.Stuart Sutherland...
Doping ions like boron and phosphorus are selectively implanted on the wafer surface to define semiconductor regions with precise concentrations. Etching Unwanted material is selectively removed by wet etching using chemicals or dry etching using reactive plasma to expose the underlying layer. Deposition ...
Dear Forum users, I implemented with verilog a simple 32 bit wide COUNTER. Then I read the counter out with Nios and I implemented on my radar
