truncate the 32-bit width to match the 1-bit width. If you know in the program that it is indeed an assignment, the reg type variable is a one-pass, so you can not follow this warning, the program shown in 6.4. You can see that you really need to assign a value in the Reg variable. If you want to eliminate this warning, you can use the modification program shown in Figure 6.5. 0 will be changed to 1 ' B0, quartus if the variable is not assigned to th

AbstractIn the DE2-70, just after a NiO II system was installed on Quartus II, almost all of us would encounter a critical warning: "Critical warning: timing requirements for slow timing model timing analysis were not met. see report window for details. ", how can we solve it? IntroductionUse environment: Quartus II 8.1 + NiO II eds 8.1 + DE2-70 (Cyclone II ep2c70f896c6n) James and John have recently wo

0. IntroductionIn the use of quartus software, often occasionally found some small tricks, the purpose of this article is to summarize the search or find tips, this article has been updated for a long time.1. Template features in QuartusRecently found a good place in Quartus II's menu: language template.You can see the language templates for Verilog HDL, SystemVerilog, VHDL, AHDL,

I don't know if you're using Quartus II 15.0 in a Windows 10 64-bit system environment. No, the process of creating a new project is to select a list of devices that cannot be pulled down and see only one device model, as shown in 1.Figure 1at first I made the mistake of thinking that the Cyclone IV E series of the Quartus II 15 software contains only one device. Later, after trying to find the left mouse b

AbstractIt cannot be detected in SignalTap II Reg and wire. It is mainly because of the Quartus II connector, Which is set in the Quartus II connector, you can increase the number that SignalTap II can detect. IntroductionUse environment: US us II 8.0 In (original) How to Use SignalTap II to inspect Reg and wire values? In (SOC) (OpenGL) (Quartus II) (SignalT

Quartus. Measure: ignore it and avoid affecting usage. 4. Warning (10240): Maid (153): inferring latch (es) for variable "lut_data ", which holds its previous value in one or more paths through the always construct Explanation: signals are integrated into latch. There is a competition between the latch en and the data input port. Measure: extract the counter from it. 5. Warning: 12 hierarchies have connectivity warnings-see the connectivity

There are two ways to quartus software allocation pins, one is to select the menu "Assignments->pins" into the Pin assignment view manual allocation, the second method is to use the Tcl script file automatically assigned. Here I will introduce the second method.1. Generate Tcl file, operation in legend orderWhere the TCL Script file name is the file path2 Locate the "set_location_assignment" field edit pin.The first time the formulation, there is no s

I used the simulation software of Quartus II 13. When I was doing a VGA experiment, I used 640*480 images, so I needed 307200 * 1bit Rom. However, the maximum Rom size that megawizard-plug-in-manager can generate is 65536 * 1bit. 1 and 2. Here we will talk about how to increase the ROM size. First, follow the general Rom steps to create the ROM file you need, for example, I create a mem. v's file election lasted 65536. open the file and modify the thr

simulation tool from Quartus, so we need to set the native link option.A) or in the Simulation Settings page, set the Native Link dialog box. We're here because we need the tool to invoke the excitation automatically so checkb) Click on the test benches on the right and we need to set up an associated test bench here.Here is a dialog box that lets you specify test bench, because we didn't specify any test bench before, so this is blank.c) Specify tes

1, [Problem] pin planner usage problems: In Quartus I 7.2, Time Series Simulation However, the timing simulation changes once pin planner is used to set the pin, which is inconsistent with the functional simulation results and is not an ideal result. What should I pay attention to when using pin planner? [Answer] If timing simulation is performed when no pin is set, the subsequent simulation will be inaccurate. Because after the PIN is set, y

AbstractWhen we want to send the entire Quartus II project to others through email or MSN, we want the entire project to have the least number of records, how can we optimize our dynamic route? IntroductionAvailable versions: Quartus II versions Sometimes a friend will send me a whole Quartus II project through email or MSN for a study. There was a project na

Quartus II software commonly used in the allocation of pins in two ways, one is to select the menu "Assignments->pin Planner" into the PIN allocation view manual distribution; The second method is to automatically allocate the TCL script file. First of all, introduce Quartus II QSF documents and TCL documents. The QSF (Quartus settings file) file is an engineeri

Quartus II is a powerful EDA software. In this inherited development environment, PLD users can complete a full set of PLD development processes, such as editing, compiling, simulation, integration, layout and wiring, timing analysis, generating programming files, and programming.Quartus II manages files in projects. This ensures the independence and integrity of design documents.Because Quartus II has many

AbstractThe US us II environment will place all the cases under the root project, causing too many root project cases and inconvenient management, if you can place the final result system under another category, it will help you manage it in the future. IntroductionUse environment: US us II 8.0 In (original release), how does one eliminate the code left by the embedded part of the system? I have proposed a project management method in the (SOC) (system definition) (system, leave the root cat

Jobs after installing Quartus II 6.0 1. Install the quartusii_60_sp1_pc patch. 2. Modify the license. dat, replace xxxxxxxxxxxx with your Nic Mac, and copy it to the Quartus II installation directory c:/Altera. (For nic Mac, use ipconfig-all in the DOS window and remove the-number.) (you must remove "-" from the MAC address; otherwise, it will fail) 3. overwrite the sys_cpt.dll file. Sys_cpt.dll file pat
