This application note shows how a Xilinx CoolRunnerTM-II CPLD can be used as a simplelogical switch that can quickly and reliably select between DIFFERENT MPEG video sources. Thesource code for the design is available on the Xilinx website, and is linked from the “VHDLCode” section. The code can be expanded by the user to perform additional operations usingthe remaining CPLD resources

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address DIFFERENT problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.

Field Programmable Gate Arrays (FPGAs) are becoming a critical part of every system design. Many vendors offer many DIFFERENT architectures and processes. Which one is right for your design? How do you design one of these so that it works correctly and functions as you expect in your entire system? These are the questions that this paper sets out to answer.

The duty and the frequency were adjusted by changing the time constant and the way of charging and discharging of the capacitor， the width of frequency was adjusted by using DIFFERENT capacitors provided with multiple switch， the amplitude of output voltage was adjusted by sampling voltage and using in-phase amplifier circuit，the ability of driving loads was raised， the circuit can be used as squarewave signal generator whose frequency and amplitude can be adjusted. The final simulation results of Multisim 10 and the tests of applicable circuit show that the performance indicators of the circuit meets the design requirements.

Generating next numbers in SQLServer should not be a problem. But problems arise when a customer asks for DIFFERENT types of next numbers that you cannot generate directly from SQL Server. This brief article describes how you would tackle this problem in DIFFERENT scenarios.

This model simulates a CDMA2000 1xRTT Forward link (between Base Station and Mobile Station). In particular, it simulates the Radio Configuration 3 of a Forward Fundamental channel. The block CDMA2k: Initial settings allows you to set DIFFERENT parameters such as data rate, Power Control SubChannel insertion rate, spreading code index, QOSF index and the channel model.

The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a DIFFERENT corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.) I have attempted to provide copious comments in the code and hope that a knowledgeable C programmer can quickly map the approach as described in the paper to what is in the program.
