AbstractDE2-70 beginners often encounter this warning message about how to determine the DE2-70's "error: Can't place pins assigned to pin location pin_ad25 (ioc_x95_y2_n1)? (SOC) (Quartus II) (DE2-70, but at the time, I have understood why I want to solve this problem (because I didn't understand it at the time). I will discuss it again in this article. IntroductionUse environment: Quartus II 10.1 + DE2-70 (Cyclone II ep2c70f896cn) This article

configuration is complete, these pins become input tri-states and are set to high level by the internal weak pull-up resistor. In the as mode, the DATA0 receives the data (2nd foot) of the configuration chip.7. DCLKPS mode is input, as mode is output. In PS mode, the DCLK is a clock input pin that is the clock that the external device transmits the configuration data to the FPGA. The data is on the rising edge of the DCLK data, in the as mode, the DC

There are more and more USB devices, such as USB mouse, keyboard, card reader, and USB camera. Therefore, the USB interface after the motherboard panel is insufficient. In addition, if too many USB devices are used in the motherboard I/O, it is likely to cause a USB device conflict or instability. Therefore, almost all mainstream boards provide built-in USB extended interfaces. However, it is difficult for users to connect to the built-in USB Extended Interface. First, we need to prepare a USB e

An error appears when the ISE is routing the layout.There are two possible reasons for the "Clock_dedicated_route" error:1. There is a clock you do not put to the global clock or local clock pin, the layout can not be used as a clock to allocate resources.2. Is you want to output a clock signal on Io, but you do not use the correct method, such as in Spartan6 you must use the ODDR register output, and not directly to the clock to a direct connection to the IO signal.Here's how to fix it:1. The s

Multi-function Selection of pins involved in FPGA: some pins can be allocated as common I/O pins or programming pins. By default, these special pins are used as programming pins. If you want to use these

The following error message is displayed during compilation of the Quartus II project. For details, see: The pin_ae24 pin is used in the project, but this pin has dual-function pins. Therefore, you must configure the pin before use, that is, whether it is a common pin or a second function pin. The specific configuration is as follows::Click the icon or select from the menu bar.Or Select device and pin options On the settings page, select the d

Prior to the simple design, the distribution of pins less, the Pin planner one input. Now in a large system, so it is too troublesome to search the Internet to use TCL files to allocate the Pin method.The steps are as follows:First generate TCL file, specifically project--generate TCL files for project, note Do not tick the include default assignments option, after the first tick, prompt error.Then distribute the
