The standard describes extensions to the Tool Command Language (Tcl): commands and arguments for annotating a design hierarchy which has been read into a tool. Semantics for inferring additional elements in the design from the intent are provided in the standard.
The Vivado Simulator is a component of the Vivado Design Suite. It is a compiled-language simulator that supports mixed-language, Tcl scripts, encrypted IP and enhanced verification. The Vivado IP Integrator allows engineers to quickly integrate and configure IP from the large Xilinx IP library.
The waveform viewer in Xilinx Simulator supports virtual bus, signal grouping, analog view & protocol viewing features. It also supports UVM 1.2 and functional coverage for advanced verification. It supports both GUI and batch mode via TCL script and allows simulation of encrypted IPs.
The Tcl programming language was created in the spring of 1988 by John Ousterhout while he was working at the University of California, Berkeley. [14] [15] Originally "born out of frustration", [11] according to the author, with programmers devising their own languages for extending electronic design automation (EDA) software and, more specifically, the VLSI design tool Magic, which was a ...
wish (Windowing Shell) is a Tcl interpreter extended with Tk commands, [1] available for Unix-like operating systems supporting the X Window System, as well as macOS, Microsoft Windows, [2] [3] and Android. [4] It provides developers the ability to create GUI widgets using the Tk toolkit and the Tcl programming language. [5] [6]
Expect is an extension to the Tcl scripting language written by Don Libes. [2] The program automates interactions with programs that expose a text terminal interface. Expect, originally written in 1990 for the Unix platform, has since become available for Microsoft Windows and other systems.
The command syntax shows some characters in a mixture of upper and lower case. Abbreviating the command to only sending the upper case has the same meaning as sending the upper and lower case command. [3] For example, the command “SYSTem:COMMunicate:SERial:BAUD 2400” would set an RS-232 serial communications interface to 2400 bit/s.
Since 2012, Xilinx ISE has been discontinued in favor of Vivado Design Suite that serves the same roles as ISE with additional features for system on a chip development. [8] [9] Xilinx released the last version of ISE in October 2013 (version 14.7), and states that "ISE has moved into the sustaining phase of its product life cycle, and there are no more planned ISE releases."
