The Vivado Tcl Store is a scripting system for developing add-ons to Vivado, and can be used to add and modify Vivado's capabilities. [19] Tcl is the scripting language on which Vivado itself is based. [19] All of Vivado's underlying functions can be invoked and controlled via Tcl scripts. [19]
SCPI commands are ASCII textual strings, [5] which are sent to the instrument over the physical layer. [5] Commands are a series of one or more keywords, many of which take parameters. In the specification, keywords are written CONFigure: The entire keyword can be used, or it can be abbreviated to just the uppercase portion. Responses to query ...
A Tcl script consists of a series of command invocations. A command invocation is a list of words separated by whitespace and terminated by a newline or semicolon. The first word is the name of a command, which may be built into the language, found in an available library, or defined in the script itself. The subsequent words serve as arguments ...
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 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.
Push a null reference on the stack. Base instruction 0x71 ldobj <typeTok> Copy the value stored at address src to the stack. Object model instruction 0x7E ldsfld <field> Push the value of the static field on the stack. Object model instruction 0x7F ldsflda <field> Push the address of the static field, field, on the stack. Object model ...
An HDL simulator — the program that executes the testbench — maintains the simulator clock, which is the master reference for all events in the testbench simulation. Events occur only at the instants dictated by the testbench HDL (such as a reset-toggle coded into the testbench), or in reaction (by the model) to stimulus and triggering events.
Early ASICs used gate array technology. By 1967, Ferranti and Interdesign were manufacturing early bipolar gate arrays. In 1967, Fairchild Semiconductor introduced the Micromatrix family of bipolar diode–transistor logic (DTL) and transistor–transistor logic (TTL) arrays.
