Frequently Asked Questions

To uninstall Sigasi HDT, do the following:

• Remove your installation directory (e.g. hdt at the top level)
• Remove your workspace (e.g. sigasi-workspace)

Sigasi HDT has an automated update system. When updates are available, you are notified by a pop-up window called Updates Available in the bottom right corner:

If you want to install the updates, click anywhere in the pop-up window. After a few seconds, a new window will appear with further instructions.

The updates can be postponed by closing the pop-up. You can perform the updates at any time by clicking the update-icon in the status bar at the bottom of the screen.

If the updates are not automatically fetched from our update server (https://update.sigasi.com) you are probably behind a firewall or proxy server. You can configure HDT's proxy settings in Window > Preferences > General > Network connections. If you can not add a firewall exception for our update site, the fallback solution is to download the complete application from our website. You can completly replace your old installation; all settings are stored in your workspace (the default is workspace-sigasi in your home directory).

Sigasi HDT is tested on Fedora Linux 9 x86, on Windows Vista (for 32 bit) and on Mac OS X Leopard.
It should work on most recent x86 Linux distributions, on Windows XP and up and on Mac OS X. We recommend at least 1GB of memory, and you need about 200MB of free disk space.

Sigasi HDT logs all internal errors to a log file. You can find this file in:
workspace-sigasi/.metadata/.log

This file is also reachable in Sigasi HDT itself via Help > Open log.

The log file contains no sensitive information about your organization. On some occasions, the Sigasi Team may suggest to send them the log file to debug or improve the product. However, the option to do so or not remains yours.

Each time you start Sigasi HDT, the program checks to see if there are new updates from our update website (currently located at IP 195.144.71.15). Sigasi HDT downloads the updates in the background and, when done, it asks you if it can install them.

You can set your indentation preferences (select tab characters or space charactes) in Window > Preferences > VHDL > Formatting.

We have released support for block editing in Update 2009-07-17.

Note that in many cases where you are used to using block editing (e.g. instantiating an entity), you may not need it any more, thanks to intelligent code completion (see this blog post).

Many actions can be accessed using your mouse and using a keyboard shortcut, e.g. copying text can be done either by clicking Edit > Copy or by pressing CTRL-C. Of course, pressing a key combination is a lot faster than clicking in a menu.

MouseFeed pop up Whenever you use your mouse for something that also has a key binding, the MouseFeed function tells you what this keyboard shortcuts is. This will help you remember keyboard shortcuts for the actions you use most often.

The easiest way to avoid getting these pop ups --and gain a good deal of development speed-- is by using keyboard shortcuts when possible.

For now, we only support VHDL. However, in the future we plan on supporting Verilog and SystemVerilog and perhaps other languages as well.

If you ever want to get back to your old tools (but we hope you won't), you'll have absolutely no trouble doing so. All your files are just the way you left them, except that we created two hidden files in your project folder (.project and .libraries.xml). You can just leave them sitting there or you can delete them after you stop using our tool.

In short: you are not locked in at all!

You do not have to change your directory structure, the names of your VHDL files or anything in your project folder. The only thing Sigasi HDT does, is add two hidden files with project information.

Yes, we assembled a cheat scheet with all important shortcuts on one page.

Furthermore the manual contains a chapter with the top 11 keyboard shortcuts and a reference of all keyboard shortcuts.

No, you get the "full monty." All features are available in the free trial.

Just click Help > Welcome.

Most settings can be changed in Window > Preferences. In this dialog, you can either browse the menus to the left, or search for an item in the search field in the top left.
