Solving staffing problems with branch-bound method (personnel assignment problem)

Recently exam Bo master relatively busy, first put the idea of simple to say, figure and code after the test to fill.Staffing issues, that is, the collection of staff and work set, to find the most reasonable arrangements.For the Employee collection p, the employee collection is given a certain order according to an F, which requires the work arrangement in that order P (i).For working set J, you can sort by partial order and have a partial order to arrange the work.For each employee correspondi

will enter the wrong state. This foot cannot be used as a normal I/O pin. The nstatus foot must pull up a 10K ohm resistor.Conf_done.This is a dedicated configuration state foot. Two-way foot, when it is output foot, is open drain. When the pin is output as a status, it is set to low level before and during the configuration. Once the configuration data is received and there are no errors, the initialization cycle starts and the Conf_done is released. When entering a pin as a state, when all da

Ubuntu under Xilinx Platform Cable usb/altera usb-blaster/seed XDS-560

Under non-root permissions to run the IDE, such as VIVADO/QUARTUS/CCS, need to use JTAG when the issue of permissions, almost all USB debugging devices under Linux will encounter this problem. Here is an example of how to solve this problem with Xilinx Platform Cable USB.After plugging in the USB, view the deviceLsusb001 006View permissions for this devicels -l/dev/bus/usb/001/006CRW11895 24 :/dev/bus/usb/ 001/006You can see that the current user does not have executable permissions, and other

Further description of the pin in Altera FPGA

Recently, the great god of end China, a faint bean, published the blog fpga r D path (25)-pin, I just got a new book titled deep understanding of Altera FPGA application design. Here we will organize the knowledge of the two. I/O feature notes for the cyclone IV device will be added later. In the previous article, the pin introduction in Altera FPGA has provided a brief and comprehensive description of the

Reproduced the basic logic unit comparison of Xilinx and Altera FPGAs

Tribute to the originalHttp://blog.sina.com.cn/s/blog_6276db0e0101ary8.htmlTo compare Xilinx and Altera FPGAs, it is necessary to understand the structure of two giant FPGA, because of their respective interests, the two FPGA structure is different, the parameters are different, but can be unified to the LUT (look-up-table) lookup table.Take the example of Altera's Cyclone II series Ep2c35, as well as the xc3s500e of the Xilinx spartan-3e series. You

FPGA learning notes Altera FPGA using JIC file to configure the Cure tutorial (GO)

Many of the friends who have done microcontroller know that after the MCU is burned to write the program firmware, then the program firmware is stored inside the MCU. The program can continue to operate even if the MCU is powered off and then re-energized. This is because the firmware of the MCU is written to write the program firmware to the MCU on-chip program memory ROM, and most modern MCU this ROM is flash memory. Flash memory can be power-down to keep data, so can realize the power-down pr

FPGA Fundamentals 2 (logical Resources--slices VS le comparisons in Xilinx Altera FPGAs)

Source: http://www.union-rnd.com/xilinx-vs-altera-slices-vs-les/ObjectiveOften a friend asks me, "Am I using a FPGA or X-Home FPGA for this program?" Do they have enough capacity? How do they compare their capacity? "Of course, most of the time, when I design for the customer, I will use the highest capacity products directly, because our products are not sensitive to cost. However, this is still a comparison of the two products, simply write some of

Solution to the top-level schematic of Modelsim-Altera Simulation

Solution:First, you need to convert the. BDF schematic file to a standard description file supported by third-party EDA tools such as OpenGL. In Quartus, keep *. BDF is in the active window status. Run the [file]/[Create/update]/[Create HDL design file for current file] command. In the pop-up window, select the file type as "maid, output *. V top-level file.

FPGA timing constraints (Altera timequest)

A good timing constraint can be used to guide the layout and wiring tools to weigh and obtain the optimal device performance, so that the design code can reflect the designer's design intent to the greatest extent possible. 2 timequest is an ASIC-style static timing analysis (STA) tool added by Altera to the 6.0 software. The Synopsys Design constraints (SDC) file format is used as the time series constraint input. 3. timequest checks the creation tim

Two companies on the pin type of the detailed definition, although many similar, but there are a lot of different Oh!!!(3) Altera's IO feature does not have a pull-down resistor! Xilinx's IO structure also has a pull-down resistor.I developed a project encountered such a problem: the transmitter, the power is required to output low level.
