(1) functions: 01 H, 07h, and 08 h
Function Description: reads a character from a standard input device (for example, a keyboard. The interrupt will remain in the waiting state during the processing until the characters are readable. This input can also be redirected. If so, you cannot determine whether the file has reached the end of the file.Entry parameter: Ah = 01 H, filter out control characters, and echo= 07 h, but the control characters are filtered out, not echo= 08 h. filter out the con

, providing an automatic Address allocation tool.
You can also set the address in the offset address and range fields. Address editor is enabled only when the IP address block diagram contains the IP core of a bus host (such as ipvq7.
Running design rule checks
Vivado checks design rules in real time. However, errors always occur. For example, the frequency on the clock pin may not be set correctly.

Xilinx-based Synthesize
The so-called synthesis means to translate design inputs such as the HDL language and schematic diagram into logical connections (I .e., network tables) between logical units registered with, or, non-users and RAM and triggers ). Optimize the logical connection generated based on the target and requirement (constraints.ISE-XST

The variables in the Verilog HDL language are only two categories of data types, wire and register Reg.
The network cable type represents the physical connection between Verilog HDL structured components, whose value is determined by the value of the source device that drives it, and the default value of the network cable is high impedance z if no drive source is connected to the network cable.

Cadence has two product chains: IC and PCB. PCB products are further divided into Po series and PS series. Po is the orcad series, and PS is the high-end series. Some people call it the allegro series, which is not accurate.
Before the acquisition of orcad, Cadence used a schematic tool called Concept HDL. The PCB tool was Allegro, the PCB editor, and the SI tool (for signal integrity analysis ).
Orcad has three tools, schematic tool caputre CIS,

HDL: Hardware Description Language of hardware discription language, which describes the operating status of the FPGA/CPLD internal logic gate to implement a certain circuit.
With the development of EDA technology, designing PLD/FPGA using hardware languages has become a trend. Currently, the hardware description languages include VHDL, OpenGL, superlog, system C, cynlib C ++
