As a user of 3 different computers I've always had an issue of keeping a single project up to date. I have 2 desktop computers, 1 connected to the internet and the other on it's own network apart from the internet. The 3rd computer is a laptop connected to the internet.
I started out recently reinstalling the same OS (winXP SP3) on all 3. This gave me the chance to install the same Xilinx ISE14.1 software on all 3 as well. Also I copied a ISE project file to all 3.
This gave me a chance to experiment with a piece of software called
Powerfolder. The review
here does not seem to be up to date. I downloaded it to laptop first (which had older updates to my project files) and then the desktop connected to the internet. Then I pointed it to the common (same name) folder for the ISE project on both computers. The verilog files were auto-updated on the laptop right after installing Powerfolder to the desktop! Very easy.
The total time for doing this was <15min's, and all it asks for is your email and an access password. You are limited to 2GB and 5 folders in the free version. I'm not sure how it all works or where the info is stored, but since this project is in it's infancy I have no concerns of security
yet.
I have yet to try Powerfolder on the "secured" desktop that is on it's own network.
