What is Xprop?

The xprop utility is for displaying window and font properties in an X server. One window or font is selected using the command line arguments or possibly in the case of a window, by clicking on the desired window. A list of properties is then given, possibly with formatting information.

What is Xprop simulation?

The ‘xprop’ simulation technology employed by recent versions of Synopsys’ VCS will replace every X it encounters with both a 0 and 1 to calculate all possible values, and then merge them to decide which value should be driven to the output.

What is SDF simulation?

The standard delay format or SDF contains timing information of all the cells in the design. It is used to provide timing information for simulating the gate- level netlist. The dynamic simulation method for gate-level design verification is still dominant, and is used extensively by designers.

What is a VCS DVE?

Introduction. The Synopsys simulator is called VCS, but it is used through an interface called Discovery Visual Environment (DVE) which is an interactive Graphical User Interface (GUI) used for debugging SystemVerilog, VHDL, Verilog, and SystemC designs.

What is SDF file used for?

The Spatial Data File (SDF) is a single-user geodatabase file format developed by Autodesk. The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 SDF format version SDF3 (based on SQLite3) uses a single file.

What is GLS SDF?

SDF. o Standard delay format. o Netlist : 2 things. o Gates(standard cells: AND, OR, etc) o IOPATH delay.

What is VLSI and Verilog?

Advertisements. Verilog is a HARDWARE DESCRIPTION LANGUAGE (HDL). It is a language used for describing a digital system like a network switch or a microprocessor or a memory or a flip−flop. It means, by using a HDL we can describe any digital hardware at any level.

What is ‘xprop’?

The ‘xprop’ simulation technology employed by recent versions of Synopsys’ VCS will replace every X it encounters with both a 0 and 1 to calculate all possible values, and then merge them to decide which value should be driven to the output.

How do I use xprop in Linux?

Summary. The xprop utility is for displaying window and font properties in an X server. One window or font is selected using the command line arguments or possibly in the case of a window, by clicking on the desired window. A list of properties is then given, possibly with formatting information.

What is the use of VCS xprop?

VCS Xprop. VCS® Xprop is designed to help find X-related issues at RTL and reduce the requirement for lengthy gate-level simulations. The simulation semantics of conditional constructs in both HDL languages, Verilog and VHDL, are insufficient to accurately model the ambiguity inherent in un-initialized registers and power on reset values.

What is X-Propagation at RTL in VCS®?

With the new X-propagation support at RTL in VCS®, engineers can now save time and effort debugging differences in X-modeling between RTL and gate-level simulation results. VCS® Xprop is designed to help find X-related issues at RTL and reduce the requirement for lengthy gate-level simulations.
