After the system is reinstalled today, install the software. quaruts and orcad are mandatory software on my computer. I have not found any problems before, but it is not smooth today. orcad cannot be installed all the time. The following error is reported:

Find the ModelSim. ini file under the Modelsim installation directory.
Remove the read-only attribute of ModelSim. ini.
Open the Quartus software. Select launch simulation library compiler.
Select the simulation tool ModelSim.
Set the Modelsim path.
Select the desired device.
Select the library language.
Select an appropriate output path.
Start compilation.
After compilation, modify the attributes of the ModelSim.
In Quartus II 10. 0, selectAssignments> device and pin Options> dual purpose pins, You can set some dual-function pinsUse as regular I/O. HoweverData [1]/asdoAndFlash_nce/ncsoBut cannot be set. This is the GUI of Quartus II 10.0.Program. So what should we do?
It is easy to do, because the GUI configuration is eventually mapped to the configuration file. The dual-function pin is configured inProject nam

Measure: ignore it and avoid affecting usage.

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.

When using someone else's project, sometimes he cannot find his pin file, but he can save the bound pin and output it to the file.
Method 1:
View the pin binding status. Choose Quartus> assignment> pins to open the FPGA pin interface. In this menu, you can save the pin files in CSV format (in table format) and Tcl format.
Step: file-> export... -> Select the Save name and save format.
Method 2:

A problem occurred during the experiment today: Can't place pins assigned to pin location pin_108,
Info: PIN usb_cs _ is assigned to pin location pin_108 (ioc_x28_y2_n0) info: PIN ~ Lvds41p/nceo ~ Is assigned to pin location pin_108 (ioc_x28_y2_n0)
The 108 pin is I/0 reusable nceo. That is, the configuration process is used as the nceo, and the work process is used as the general I/O.
After finding a solution for a long time, I first changed the active mode to the passive mode assignment -->
During the summer vacation, a key in Quartus II is accidentally clicked, And the testeditor tab cannot be found, after opening multiple files, you do not know how to selectively close a file. If it is minimized, it is like on the maxplus II interface. But I always think that tabs are much easier to use. However, after searching for a long time in the menu, you do not know which option can call up the tab. The description is as follows:

Last semester just learned the principle of single-chip microcomputer, so get started DE2 board relatively easy, RAM and ROM concept has been established earlier. After playing the call of duty after some tiredness, write a DE2 board on the SRAM on
The PWM output controls an LED light and adjusts the duty ratio of the output signal to change the brightness of the LED light.
Because the block module is parallel, it is very convenient to produce a clock module, which no longer needs to be

Recently began to learn Verilog HDL language, right on the hand there is a DE2 from the seniors borrowed an FPGA development board. Take advantage of the holidays to learn.
Because there are some C-language basics, it is very fast to look at Verilog
For example, create a new vCode, Select Edit> insert template, or click to insert the preset OpenGL template.

In the previous post, I posted [materials]. It is required to learn timequest. The timequest cookbook mentioned in this
/install_patch
./Nios2_sp1/install_patch
./Quartus_sp2/install_patch
./Nios2_sp2/install_patch
When any of them ask you install path, specify
/Opt/altera
Installation will take a long time, especially for quartus and quartus_sp1, sp2.
The programs will be installed in the following directories:
Quartus =/opt/altera/

Typical CAD Process
1. Start
2. Create a project
3. Design the input using the OpenGL code
4. Compile and design the circuit
5-pin allocation
6. circuit designed by Simulation
7 Programming and configuring FPGA Devices
8. Test and Design circuit

AbstractThis article describes how to use Modelsim for pre-simulation and use Quartus II and Modelsim for post-simulation.
IntroductionUse environment: US us II 8.1 + Modelsim-Altera 6.3g
Because FPGA can repeat the programming process, many developers will not use testbench. They will directly use the programmer program of Quartus II to open the Development
