In Quartus II, timing analysis is static timing analysis, that is, Stas (static timing analysis ). The object analyzed by STA is a synchronous logical circuit. The path is used to calculate the total latency and analyze the relative relationship between time sequences. The most popular analysis tool in the industry is Primetime, which is based on Altera us. STA is mainly for analysisFmax,Tsu,Th,TcoThese parameters. These parameters are defined as fol

Two 256kx16bit SRAM memory is used in diy_de2. The read and write operations of SRAM are relatively simple. The operations can be divided into hardware debugging and software debugging. Debugging environment: Quartus II 9.0 + niosii 9.0 1. hardware debugging That is to say, the simplest way to read and write the SRAM is to build the SRAM project and read the SRAM project respectively. First, write the SRAM. when the power is continuously on, rea

Abstract"Leaving target processor paused" is a warning message that many beginners of nioii often encounter. I met again today. I will share my debugging process with you. IntroductionUse environment: Quartus II 8.0 + DE2-70 (Cyclone II ep2c70f896c6n)+ TRDB-LTM In the (original scheme), how does one determine the valid parameter information of the "leaving target processor paused" of the niosii? In the (IC design) (SOPC us II) (Systems builder) (n

tested by bingo countless times to form the final code. It can adapt to N buttons in terms of function, and uses the single chip microcomputer to eliminate jitter. You need to analyze the specific code implementation process on your own. This module is easy to transplant. The following is the sample code in the OpenGL module: /*************************************** ********** * Module name: key_scan_jitter.v * Engineer: crazy bingo * Target device: ep2c8q208c8 * Tool versions:

Under non-root permissions to run the IDE, such as VIVADO/QUARTUS/CCS, need to use JTAG when the issue of permissions, almost all USB debugging devices under Linux will encounter this problem. Here is an example of how to solve this problem with Xilinx Platform Cable USB.After plugging in the USB, view the deviceLsusb001 006View permissions for this devicels -l/dev/bus/usb/001/006CRW11895 24 :/dev/bus/usb/ 001/006You can see that the current user do

following different methods of synthesis. 　　1.2.1 to reduce delay by changing the way the line goes Take the Altera device as an example, we can see a lot of floorplan in the timing closure She in Quartus, we can divide the She by row and by column, each bar represents 1 lab, 8 in each lab or 10 le. The relationship of their line-delay is as follows: the same lab (fastest) 　　1.2.2 to reduce delay by splitting the combinatorial logic As the general

Introduction: This paper aims to generate positive cosine wave (without using IP cores) through this algorithm.One. Simulation WaveformAs shown above, Dout_sin and Dout_cos output trigonometric function values in complement form, where DOUT_VLD is used to indicate the validity of the signal.Two.

1. Perform the Modelsim installation procedure first 2. Execute keygen program--keygen.exe, generate license file 3. Create a new folder in the Modeltech_6.2b folder installed in the first step, named Flexlm, to copy the license file from the second step into the FLEXLM folder 4. Modify the environment variables as shown below The variable name is: Lm_license_file The value of the variable is: C:\Modeltech_6.2b\flexlm\license.dat Where the var

The principle of GMSK modulation is very simple.is the Gauss filter before the MSK modulation.In the implementation there are such methods, first producing Gaussian coefficients, symmetrical ascending and descending po coefficients. Input a symbol, carry on the sampling, pass the Gaussian filter, the output of the filter does the symbolic summation.The accumulated output is compared with the upper and lower values, i.e. the value greater than pi minus 2PI or less than-pi to add 2PI. The results

We know that digital EDA simulation software is commonly used in three (Big 3), Synopsys VCs, (Verilog Compiler Simulator) Cadence's Ncsim (Incisive Enterprise Simulator core simulation engine), and Mentor graphics of the Modelsim/questa. When I first started using Ncsim, I often wondered what NC meant. Ultimately, the almighty search engine helped, cadence of the Ncsim, from the document [1] and [2] can be seen Nc/ncsim means na

The distinction between the IC front-end design (logical design) and the backend design (Physical Design): whether the design is related to the process or not, the result of the front-end design is the gate-level network Table circuit of the chip. The front-end design process and EDA tools are as follows: 1. Architecture Design and verification: divide the overall design modules as required. For architecture model simulation, you can use Synopsys's cocentric software, which is a simulation tool

functions are checked. Before simulation, you must first use the waveform editor and HDL to create a waveform file and a test vector (that is, combine the input signal concerned into a sequence ), the simulation results generate a report file and the output signal waveform, from which you can observe the signal changes of each node. If an error is found, the design modification logic design is returned. Commonly used tools include Modelsim of model t
