) ≥ 0 The following formula is introduced: Tclk1 (max) + TCO (max) + tpcb (max)-tclk2 (min) ≤ tclk + ftsu According to the official data manual of Altera: Input delay max = board delay (max)-board clock skew (min) + TCO (max) The system parameter formula is as follows: Input delay max = tpcb (max)-(tclk2 (min)-tclk1 (max) + TCO (max)2. Minimum input latency The minimum input latency (input delay min) is the minimum output latency (TCO) of the device w

FPGA_VIP_V101 has been introduced for more than half a year, the functions of the routine has been transplanted, the main reference Crazybingo routines for porting and the development of a combination of board design a few instances of the routineMainly includes:Hardware configuration:FPGA:EP4CE6E22C8N (6k logical resource, can be nios developed)sdram:hy57v641620 (32M, can do video image cache, Nios memory)

After serialization of niosii, many of my friends joined my QQ and NIOS technology group and found some problems through some time of observation and understanding. Many beginners have no idea about the development process of the Nios II. More specifically, they do not know about the Quartus and NIOS development environments. Many people suggest that I use video

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 pins in the middle of the file in the following format.Set_location_assignment pin_

and must be re-downloaded when power is added. In an experimental system, a computer or a controller is usually used for debugging, so PS can be used. In the practical system, in most cases, the FPGA must be actively guided to configure the operation process, when the FPGA will actively from the peripheral dedicated storage chip to obtain configuration data, and this chip in the FPGA configuration information is designed by the ordinary programmer in the POF format of the file into.1.

processing tasks such as digital filters. The USRP includes digital frequency conversion, pumping value and interpolation module and so on. I did not see the Bladerf function, probably similar to USRP. One difference to note is that Ettus uses Xilinx chips, and Nuand uses Altera's chips, so it's slightly different. There are more DSP modules in the FPGA than Altera,xilinx, including pre-adder, multipliers and accumulators, while

The basic steps for porting websever from 10.0 to 11.0:1. Open the original 10.0 project file with 11.0, then open the Sopc Builder tool, regenerate the Nios system (this step is important), then go back to the Quartus project to recompile the hardware system, and finally download the. Sof to the Development Board.2. Start Nios SBT (Win7 system needs to be started as an administrator), set up a workspace di

complete the addition. Then, modify the name, as shown in. In fact, you can do this without modifying it, just to make it look simple. After the modification, we have another step to deal with. Double-click the CPU and click it, as shown in the red circle. We want to select memory as an Apsara stack, that is, read data from Apsara stack after power-on. Everyone remembers what I said when talking about parallel flash. Here we should choose cfi_flash. That is to say, after power-on or reset

I found some materials on the Internet to learn. It seems that I think the three Modelsim simulation methods are good, and I did it step by step. The results can be imagined. The problem is one by one, after two days of exploration, I still learned something and noted it down. First: the basic method for manipulating Modelsim 1.
