4. The Hostid Value column contains the dongle ID/MAC ID of the license.
For node-locked licenses (Count=Fixed), this host value must occur in the lower Local system info
area:
- Hostid val ues beginning with “T…..” are for Dongles, the corresponding Dongle ID must occur in
the Software Guard ID field, otherwise the license is not valid.
- Hostid value is a hex numer for Ethernet MAC ID, the corresponding MAC ID must occur in the
Network Interfaces Card (NIC) ID field, otherwise the license is not valid.
For floating licenses
1
, the Ethernet MAC ID must belong to the MAC IDs of the license server.
5. The Hostid Type is “Software Guard” for dongles, and “NIC ID” for Ethernet MAC IDs.
4.1.2 Compare license file and Quartus II License Setup
If the Quartus II License Setup (menu Tools – License Setup…) does not report the license as
expected, or if you want to find out which license is inside a license file, just open the license file with a
text editor. For the EtherCAT IP Core, there should be a similar line like this:
FEATURE 745C_1810 alterad 2011.06 7-jun-2011 uncounted 637F8760B8D1
VENDOR_STRING="k7ke4[...]” HOSTID=GUARD_ID=T000100052 SIGN="2DE7 A4DD[...]"
This feature line contains a license with this information:

It is a license for feature 745C_1810, which says it is a feature from Beckhoff (vendor ID 745C) for
the EtherCAT IP Core (product ID 1810).

It is a license for Altera, because it uses the Altera license deamon (alterad).

The license is valid for products which are released until 06/2011.

The license expires at June 7
th
, 2011

The number of seats is uncounted (relevant for floating licenses
1
)

The following hex code and the VENDOR_STRING (shortened) are interpreted by the license
software

The HOSTID is important, it contains a MAC ID or, like this one, a Dongle ID
(GUARD_ID=T000100052).

The last field (SIGN, shortened) is interpreted by the license software.
With this information, you can compare the license file contents with the License Setup information. If
the license is not displayed, compare the HOSTID of the license file against the NIC ID/Software
Guard ID shown in the Quartus License Setup.
For MAC IDs, make sure the network adapter is enabled. Some adapters enter a power down mode if
nothing is connected, try to connect some Ethernet device with the adapter.
From the feature line, it is not possible to determine if this is an OpenCore Plus license or a full
license. This can only be determined from the filename of the original license file from Beckhoff, or
during analysis in Quartus II.
