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

distribution files 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: Output pin configuratio

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 -->

AbstractQuartus II is a large but extremely powerful component. Beginners are often lost in the us II category, altera provides technical training for beginners, focusing on "all Chinese 』!! IntroductionQuartus II functions are even greater than Visual Studio. Even after two years of research on FPGA and niosii, many functions of Quartus II and niosii have not been used, today, we found that Altera was very keen to provide the "All Chinese" tutorial,

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: Display ta

Simulation in Modelsim requires the addition of a simulation library provided by Quartus, due to the following three areas:· Quartus does not support testbench;• Called Altera functions such as megafunction or the LPM library;• Timing simulation is done under Modelsim.The following is an example of Altera devices, how to add Altera's simulation library in

correct verification result is obtained, the design is proved correct. Circuit Verification is of great significance for FPGA casting.
