Installing Microsemi Libero 2021.3 on Ubuntu 20 LTS

Mostly based on this great tutorial : https://bobbl.github.io/fpga/microsemi/2021/04/30/install-libero-update.html

Prerequisites

1

sudo apt install libxtst6:i386 libxrender1:i386 apt-file lsb xfonts-intl-asian xfonts-intl-chinese xfonts-intl-chinese-big xfonts-intl-japanese xfonts-intl-japanese-big ksh libxft2:i386 libgtk2.0-0:i386 libcanberra-gtk-module:i386 libqt5xdg-dev:i386

You may need other QT related packages in their i386 flavour.

Get License

Create a directory for the license server (here I use ~/.local/share/microsemi/license)

1

mkdir --p /home/USERNAME/.local/share/microsemi/license

Download the “Linux Daemon” from https://www.microsemi.com/product-directory/design-resources/1711-licensing#downloads to the license directory and extract it with:

1

tar xf Linux_Licensing_Daemon.tar.Z

Create an account on https://www.microsemi.com and request a “Libero Silver 1Yr Floating License for Windows/Linux Server”. You have to enter your MAC address (12 hexadecimal digits without colons), which you can get by typing

1

ip link | grep ether

The license file is sent via email. Store the license file License.dat in the license directory.

Now the first four lines of the license file must be edited, but not the rest of the file. In the first line, replace <put.hostname.here> by localhost. In lines 2 to 4 replace PATH by the absolute path to the license daemon directory. The first 4 lines schould then look like that:

SERVER localhost 112233445566 1702
DAEMON actlmgrd /home/USERNAME/.local/share/microsemi/license/Linux_Licensing_Daemon/actlmgrd
DAEMON mgcld /home/USERNAME/.local/share/microsemi/license/Linux_Licensing_Daemon/mgcld
VENDOR snpslmd /home/USERNAME/.local/share/microsemi/license/Linux_Licensing_Daemon/snpslmd

The license manager requires that /usr/tmp exists (otherwise you get “FlexNet Licensing error:-25,234”)

1

sudo ln -s /tmp /usr/tmp

Install the depedencies

1

sudo apt install lsb

And start the license server with

1

Linux_Licensing_Daemon/lmgrd -c License.dat -log /tmp/lmgrd.log

If you get a “file not found” error, install lsb.

On my system I have the problem that the license works only for a few minutes. I don’t know why, but when I start Libero a second time after a few minutes, it doesn’t recognise the license. Stopping and restarting the license server helps:

1
2

Linux_Licensing_Daemon/lmdown -c License.dat -q
Linux_Licensing_Daemon/lmgrd -c License.dat -log /tmp/lmgrd.log

Known issues

Let’s have a look at the first lines of the license file again:

1
2
3
4

SERVER localhost 112233445566 1702
DAEMON actlmgrd /home/USERNAME/.local/share/microsemi/license/Linux_Licensing_Daemon/actlmgrd
DAEMON mgcld /home/USERNAME/.local/share/microsemi/license/Linux_Licensing_Daemon/mgcld
VENDOR snpslmd /home/USERNAME/.local/share/microsemi/license/Linux_Licensing_Daemon/snpslmd

• actlmgrdmust be a 32-bit daemon.
• mgcld and snpslmd must be 64-bits daemons.

Don’t ask me why, we went through several problems until finding this solution.

Install Libero

Download “Libero SoC v2021.3 for Linux” from https://www.microsemi.com/product-directory/design-resources/1750-libero-soc#downloads.

The downloaded binary is a self-extracting archive built with InstallAnywhere. Before executing it, set its execute bit must be set and some dependencies have to be installed:

1
2

chmod +x Libero_SoC_v2021.3_lin.bin
./Libero_SoC_v2021.3_lin.bin

Before actually starting Libero, some environment variables have to be set:

1
2
3

export LM_LICENSE_FILE=1702@localhost
export SNPSLMD_LICENSE_FILE=1702@localhost
export LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/:/usr/lib/x86_64-linux-gnu/:/usr/lib

Now, you can launch Libero SoC:

1

/opt/microsemi/Libero_SoC_v2021.3/Libero/bin
