Need to use your company EDA tools from home, here are some tips: 1) First of all, the most important solution is to speak to your EDA vendor= , I am sure all have solutions for you and some even give you a free tempor= ary license (if you are an existing customer). 2) If you have a node locked license, simply take the dongle home. 3) If you have a MAC based license then try to spoof the MAC address on you= r home PC. If this fails, buy a cheap USB Wifi dongle from eBay and try aga= in. I would recommend not using a USB Ethernet cable dongle as they tend to= go into low power mode when no cable is plugged in and you will loose your= MAC address (goes to FFFFFFFFFFFF) 4) If you use a floating license at work then ask your IT to set up a VPN c= onnection so that you can check out a license at home. Once you have a conn= ection you can use: lmutil lmstat -a to see how many licenses are available, and lmutil lmstat -A to see who has checked out a license. 5) Moving a license server home is very easy. Just make sure you have the l= icense file, license key and license utilities. For Flexnet/Flexlm, which t= he majority of EDA vendors use you only need 2 (Linux) or 3 (Windows) execu= tables. You need lmgrd(.exe) which is the license server and the daemon whi= ch is supplied by your EDA vendor. For windows you also need lmtools.exe to= setup the license server. The license key is as per point 2 and 3. 6) If you are not allowed to take the dongle home or they are shared by mul= tiple engineers then use one of those "USB over Ethernet" utilities. Make s= ure you pick one that works with USB dongles (not all do). 7) Some node locked licenses do not allow you to use Windows RDP (remote de= sktop) # ** License Issue: Cannot checkout an uncounted license within a Windows T= erminal Services guest session. Fortunately this is only applies to RDP, TightVNC, Logmein, Teamviewer etc = all work fine! As I mentioned number 1 is the option you should start with, I would NOT an= d I stress this point, use a hacked license/daemon! Not only are you riskin= g getting all sorts of nasties on your PC (which you use to access your ban= k right?) some EDA vendors can actually track where their software is used.= They might not sue you at this time but they do remember. And a final note, some of the above suggestions could be somewhat questiona= ble wrt your license agreement, if you are worried speak to your EDA vendor= , there is no point in breaking your license agreement as I am sure your ED= A vendor will help you out. Happy working from home (I have been for the past 20 years...)
