For example,

DAEMON modeltech /usr/mti5.2/sunos5/modeltech \

/usr/mti5.2/sunos5/options

A FEATURE line describes how many licenses ("tokens") are available; it contains the feature name, daemon required, most current build date authorized to run, token expiration date, number of tokens for the feature, license code, and a checksum. The features are:

vcom is a VHDL compilation feature vsim is a VHDL simulation feature vlog is a Verilog compilation feature vsim-vlogis a Verilog simulation feature

When a VHDL design is compiled, a vcom token is used. When a Verilog design is compiled, a vlog token is used. When a VHDL design is simulated, a vsim token is used. When a Verilog design is simulated, vsim-vlogis used. This is why two people running different single- language designs can work at the same time with one ModelSim PLUS product. When a design with both languages is run, one of each token is checked out.

With ModelSim EE/LNL, hdl FEATURE lines are added. With LNL (language-neutral licensing), either VHDL or Verilog - but not both - can be used. The hdl FEATURE lines are shown in the example:

hdlcom is a compilation feature used with either VHDL or Verilog hdlsim is a simulation feature used with either language

Notice the FEATURE lines. If a line is too long for the email program, a backslash ("\") appears at the end of the line. A UNIX system reads that as "whatever you read on the next line belongs on this line". So never edit out the "\" when you are transcribing a license file. Never put another character after it either.

All the important lines end in checksums. FLEXlm will let you know if you mistyped something when transcribing the license files because the checksum will not match the line's contents. (GLOBEtrotter has a utility that will report any checksum errors in a file. Use this command: lmchksum <license.file>) Lines that start with "#" are comments.
