A Test Bench

II Instantiate the synthesized netlist module FA Netlist F2 (A, B, Cin, SumStr, CoutStr)  

This test bench prints all mismatch violations that occur. 

In the following sections, we see examples of how mismatches may occur that may be caused due to different interpretations by synthesis (as compared to Verilog HDL language semantics). 

Delays specified in a design model may cause a functional mismatch between the model and the synthesized netlist. Here is an example of an adder model that uses a delay in a continuous assignment, and its synthesized netlist. 

If vectors from a stimulus file were applied, say every 1 ns, and all the module instances in the netlist represent behavioral models with no delay, the results between the design model and the netlist will be skewed because of the difference in delays. The correct approach in such a case is

New physics such as the fractional quantum Hall effect has emerged from non-magnetic semiconductor heterostructures. These systems have also been a test bench for a number of new device concepts, among which are quantum well lasers and high electron mobility transistors. Ferromagnetic 111-Vs can add a new dimension to the III-V heterostructure systems because they can introduce magnetic cooperative phenomena that were not present in the conventional III-V materials. 

Two demonstration cases of an ICE starting have been done with DLCs module with a diesel engine assembled on a test bench. In this application, an additional low-power battery is sufficient because it is only used for the initial charge of the DLCs which may be performed with low current. Once the engine is launched, the alternator of the vehicle charges the DLCs. It thus results in a reduction of the size of the battery and a greater longevity of operation. 

Another approach is to write a test bench a test bench is a model written in Verilog HDL that applies stimulus, compares the output responses, and reports any functional mismatches. Figure 5-3 shows such a scenario. A test bench for a full-adder is shown next. The stimulus is read from a vector file Inputs.vec its contents are of the form ... 

The experimental tests took place on a test bench at I.F.P. Energy Application Techniques Department. The experimental set-up and testing method are the same as used by Germidis and Castagna[18], except that we have used ceramic monolith instead of a metallic monolith. Additionally the test bench was equiped with standard gas analyzers namely for HC, NOx, CO. 

The complex impedance of the surrogates was measured between 5 kHz and 1 MHz using a test bench, two metal electrodes, and an LCR meter (Agilent E4980A). A stamp ensured a constant contact pressure between electrodes and surrogate [8].

In order to reproduce both the sun s path and the rays of low incidence — or intensity, at dawn or at dusk for instance — in the most realistic way, a test bench was created. The xenon lamp was fixed, and the created test bench had to allow the textile prototype to be exposed under different angles of lighting. Fig. 21.21 represents the measurement device. 

The main objective of the abrasion test method was to determine a link between the electrical resistance and the abrasion level, which also affects the breaking load performances. A test bench for abrasion has been developed, as shown in Fig. 23.7 based on the ASTM 4157-10 standard Test Method for Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder) . This standard has been modified to measure more specifically the electrical resistance during the abrasion cycles. 

In [96] two fuel-ceU hybrid systems are analyzed with experiments on a test bench. The first hybrid system was concept 1.1 (a) with a battery, whereas the second hybrid system was concept 1.2 with a supercapacitor. It was shown that a... 

One of the most common comparisons involves supra-molecular capsules and enzymes because they share many behaviors, properties, and common features. Encapsulation phenomena reveal new concepts that clearly show interaction between substrates and enzymes in the formation of active complexes that subsequently lead to catalytic reactions and product formation. Encapsulation criteria, and the relative driving forces involved, teach about substrate selectivity typical of enzymatic reactions, therefore the future development of new self-assembled capsules and the study of their encapsulation phenomena represents a test bench to master molecular recognition. Supramolecular capsules have already acted as supramolecular catalysts that are able to accelerate chemical transformation and to steer product selectivity, but turnover ability is still the critical point that requires improvements. 

The ejector was characterized at a test bench that was equipped with a needle valve in the ejector off gas pipe to simulate the pressure drop of reformer and stack and enable a controlled back-pressure. Nitrogen was used as suction gas because of its comparable density with the expected AOG. Resulting recycle ratios as function of the adjusted back-pressure are shown in Figure 8. To investigate the influence of the ejector geometry mixing channel diameters between 2 and 4.5 mm and different nozzle positions were tested. 

If the installation includes any special facilities such as a test bench where it is necessary to establish and maintain a non-conducting location, the walls and floors must be made of non-conducting material. Their insulation value has to be proved by measuring the leakage current between at least three points on each relevant surface and earth. So a test bench against a wall would require a test at not less than three points on the adjacent wall and three on the floor. If there is an extraneous conductive part in the location, such as a metal window frame or service pipe, one of the test points should be not less than 1 m or more than 1.2 m from it. Check that the extraneous conductive part is separated from any exposed conductive part so that they cannot be touched simultaneously. If they can, the section of the extraneous part, within reach, has to be insulated to withstand a 2 kV a.c. test with a leakage current not exceeding 1 mA. 

Carrying out the work in an area set aside , delineated by barriers and screens, to prevent both unauthorised access and the tester being disturbed. In some circumstances, such as high voltage test areas, the barriers should be interlocked to prevent access while the unit is energised. People at different work stations on a test bench should be separated by insulating screens.

One important use of fault injection is out-of-context benchmarking of the error sensitivity of software components. In this type of benchmarking, fault injection experiments are conducted in a test bench that provides an artificial environment to the software component. Out-of-context dependability benchmarking provides a way to build a library of pre-validated software components, which allows the cost of the fault injection experiments to be amortized over several systems and products.
