As described, VHDL allows signals of almost any user-defined type. Thus, to model I/O impedances we create a user-defined type called uThevenin (u indicates unresolved types). This signal type ...

The VHDL code provided with this article (“VHDL Code Listing” at www.electronicdesign.com, Drill Deeper 19222) is an example of one way to implement the LED driver in a CPLD.

The core’s functional configuration is designed by VHDL code and designed input signal (test bench) for PPI 8255, which is generated by VHDL code.

The constant “Bus_parker” in the VHDL code defines the park master. After a device has access to the PCI bus, this device must start the bus access within 16 PCI clock cycles. If this start-up does ...

Okay, now we’re beginning to feel a bit like [Alice]. This tutorial shows you how to simulate VHDL code. This code is intended to run on an FPGA and includes a software-only version of the AVR 8 ...

Grenoble, FRANCE and Tbilisi, GEORGIA -- August 18, 2008 – EMCoS, a leading provider of simulation software for electromagnetic problems and data visualization, and DOLPHIN Integration, creator of ...
