File Extension Database

Open VLSI File

Files with VLSI (Very Large Scale Integration) file extensions are crucial in the world of semiconductor design. VLSI represents the process of creating integrated circuits by combining thousands, or even millions, of transistors into a single chip. This article will discuss the possible formats associated with VLSI file extensions and how to open and use them. Where appropriate, we will provide links to relevant software that can assist in opening these files.

VLSI File Types

There are several types of VLSI file extensions. Some of them are specifically related to the design and modeling of integrated circuits, while others serve different purposes in various industries. The following sections will delve into a few common VLSI file types and their uses.

GDSII File Format

GDSII, or Graphic Design System II, is a binary file format used in the semiconductor industry for integrated circuit layout. This format is widely used to store layout data for various design tools in the semiconductor industry. The data can be used for verification, manufacturing, and testing purposes. Popular tools for viewing and editing GDSII files include KLayout (https://www.klayout.de/) and Magic VLSI (http://opencircuitdesign.com/magic/).

SPICE File Format

SPICE (Simulation Program with Integrated Circuit Emphasis) is a general-purpose circuit simulation program used in the development of integrated circuits. Files with the .sp format contain circuit netlists, which describe the connectivity of nodes in a circuit. To create a simulation, SPICE-compatible software reads the netlist file and processes various analyses on the circuit. There are various SPICE simulations available online for free, such as LTSpice (https://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html) and Ngspice (http://ngspice.sourceforge.net/).

Verilog and VHDL File Formats

Verilog and VHDL (VHSIC Hardware Description Language) are two widely used hardware description languages in the design and verification of digital circuits. These languages help engineers model and simulate digital systems from simple logic gates to complex integrated circuits. Files using these languages typically have .v (for Verilog) and .vhd or .vhdl (for VHDL) extensions. Various simulation and synthesis tools support these file formats, offering different levels of functionality and complexity. Some popular software includes ModelSim (https://www.mentor.com/products/fpga/modeling_and_simulation/modelsim/), Xilinx Vivado (https://www.xilinx.com/products/design-tools/vivado.html), and Altera Quartus (https://www.intel.com/content/www/us/en/software/programmable/quartus-prime/download.html).

VLSI File Important Information

To effectively open and use VLSI files, it's essential to understand the various file types and formats and the purposes they serve. By knowing the differences between GDSII, SPICE, Verilog, and VHDL files, engineers can identify the specific software needed to open and manipulate these files. In addition, familiarity with these formats and tools can streamline the design, verification, and manufacturing processes for integrated circuits. Remember that when working with VLSI file formats, you must comply with any applicable usage restrictions or licensing agreements set by software providers or the organizations that develop and maintain these file formats.

How Can I Open VLSI File on Windows

We researched and learned that the best way to open VLSI file is to find a VLSI file in question in Windows OS File Explorer and double click on it to launch the corresponding application.
If a VLSI file is not opened in an application and you instead get a "Windows can't open a file" error message you should try looking for an application which can open the file in question.
If you know the application which can open VLSI file then run it and see if there is a File->Open main menu option in the application.
If you don't know the application which function as VLSI file opener then try to search online for "VLSI viewer", "application to open VLSI file" or "open VLSI file" queries in the search engine you like.
Install the application you found and check if it can open VLSI file

How Can I Open VLSI File on Mac OS

We recommend to find a VLSI file in question in Mac OS Finder and double click on it to launch the corresponding application.
If a VLSI file is not opened in a Mac OS application and you instead get a "There is no application set to open the file" error message you can click on "Search App Store" in the error dialog and Mac OS will show you applications compatible with VLSI file.
If you know the Mac OS application which can work as VLSI file opener you can choose the "Choose Application..." option in the error box to associate the file extension and open VLSI file in it.
If you don't know the application which can open VLSI file then try to search for "VLSI viewer", "application to open VLSI file" or "read VLSI file" queries in the online search engine you like.
Install the application you found and check if it can read VLSI file

How Can I Open VLSI File on Android

If you downloaded a VLSI file on Android device you can open it by following steps below:

In the Android apps list on your Android device find "My Files" or "File manager" app and tap to start it.
Tap on "Downloads" folder inside the app.
You should see your downloaded VLSI file in that folder.
Tap on the file. If Android device supports opening the file you downloaded it will open in the corresponding app.
If file does not open you can look for the corresponding app that can open the file by searching Android App Store for the "VLSI".
If you cannot open the file with the apps from Android App Store it is possible that the file could only be opened on desktop platforms such as Windows or Mac OS. Try searching for "VLSI viewer", "VLSI file reader" online and see if any desktop applications can open it.
It is also possible that the file you downloaded is outdated and is no longer supported.

How to Open VLSI File on iPhone or iPad

To open VLSI File on iOS device follow steps below:

We advies to open Files app on your iPhone or iPad device. You can find it by swiping down on the home screen and typing "Files" in the search bar.
Tap on the Downloads folder on the Files app home screen.
You will see all files that you recently downloaded. Tap on the VLSI file to view it.
If you have the right app that can open it it will automatically launch and open your file.
If you don't have the app which can open it you need to serch Apple app store for "VLSI". This way you can find apps which can open VLSI files.
If this doesn't help it is possible that your file could be opened only by the desktop application. To find an app which can open it on desktop look for "VLSI viewer" or "VLSI file" online in your favorite search engine.
