I. Don't forget me. The embedded logic analyzer sigbaltap II is an embedded logic analyzer that comes with Altera Quartus II. It differs from the Modelsim software simulation. It is an on-line simulation that allows you to more accurately observe data changes and facilitate debugging. Many children who have learned single-chip microcomputer think that single-chip microcomputer can be debugged in one step online, while FPGA is concurrent and cannot

(2) initialize and give data through a three-stage state machine. (3) read an "array" cyclically and feed the lcd1602 data cyclically, facilitating changes in the form of interfaces. Ii.

In FPGA design, bidirectional signals can only be used in input and output, but bidirectional signals cannot be used in internal logic. Do not use this signal. Otherwise, the tool will combine something you don't know. For a two-way port

You should read this application note early. 8. the default PLL phase compensation is C0. In other series devices, C0 is generally not used to output the clock of the external pin, while the C0 is the only PLL output that can be directly output to the external pin for clock . Privileged students found in practice that this C0 cannot be used as phase compensation. If the default C0

Don't forget automatic Address Allocation and interrupt allocation. Oh, let's start compiling. Wait ...... After compilation, we return to the Quartus interface and allocate pins Based on the Tcl script file, as shown in Next we will run the script file, compile it, and wait a long time ...... Af

to the pin. Low versions are not taken into account, so it is easy to see all low versions. The senior student is also surprised. This is the case because the senior student does not use the later version of Quartus, but he said it may be due to the current. In addition, there are several resistor throttling before the chip, and the current is very small. Add a throttling to limit the phenomenon. Alas, after a long call, the phenomenon has finally oc

A good timing constraint can be used to guide the layout and wiring tools to weigh and obtain the optimal device performance, so that the design code can reflect the designer's design intent to the greatest extent possible. 2 timequest is an ASIC-style static timing analysis (STA) tool added by Altera to the 6.0 software. The Synopsys Design constraints (SDC) file format is used as the time series constraint input. 3. timequest checks the creation time and retention time. Asynchronous signals ar

This example shows how to optimize the design sequence by reorganizing the path. First, let's look at the optimized instance Code provided in the original book. The following is the code snippet before optimization:Module randomlogica (Output Reg [7: 0] Out, input [7: 0] A, B, C, input CLK, input cond1, cond2); always @ (posedge CLK) if (cond1) out The above code is integrated in Quartus II to obtain the result shown in Figure 1.

mention that the front-end design of the chip is mostly completed by advanced EDA tools. All the designers need to do is to use the hardware description language to meet users' needs. Commonly used hardware languages include OpenGL and VHDL. simulation tools are generally Modelsim and Synopsys. If you do not need to put your own IP Core on FPGA for verification, you do not need to use the Quartus or ise tools. Because it is more than enough for desi

system. All IPcore (including the release and self-developed by Altera) are integrated into one FPGA. A single on-chip system basically contains the vast majority of online simulator functions. Any changes in hardware structure design are on the FPGA, which enables the concept of a general online simulator to be realized. For online simulation of other chips, you only need to change the ARM7TDMI JTAG IPcore module and download it to FPGA again to perform online simulation of another processor c

Both Quartus and NIOS are of version 9.1. Find information on the Internet that version 9.1 supports MATLAB r2008a, but does not support r2009a. Then, on the official website, we found that only DSP Builder of 9.1 SP2 is supported. After installing the software in the sequence of MATLAB and DSP Builder, we found that our license had very few IP addresses. (When installing DSP Builder, you are prompted to select the MATLAB version. Only r2008a and othe
