The error was reported today when the client used Modelsim fully automated simulation of the DDR SDRAM controller. I began to wonder if lattice software is too garbage, and there are weird problems. Tossing a night, found that I wronged the lattice, in fact, is the problem of Modelsim. I use the modelsim10.2, the error is like. A long time ago, a certain version will not be error, will only prompt warming.S

1 simple way to start multiple Modelsim graphics environment windows on a single computer (Windows)http://blog.21ic.com/user1/3128/archives/2010/73447.html Simple way to launch multiple Modelsim graphics environment windows on a single computer (Windows) Modelsim due to license restrictions, generally a PC can only start a window program, open the second time wil

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

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.

The author's computer was installed as a win8 system, and then opened Modelsim as usual, then jumped out of the interface:The author's Modelsim before is installed, so this interface has been explained that the current license is not installed. The solution to this problem is to reinstall the license.First copy the following two files to the Modelsim-->win64 fold

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?

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
