Hi John,
Anonymous please, as I am trying to find the truth....
I, too, have been told that LMG Models and DesignWare are together by
Synopsys Sales. In fact, I was told that:
Lsmart + Ldesignware = constant
where Lsmart is smartmodels licenses you want, Ldesignware is DesignWare
licenses you want, and constant is the total number of SmartModels plus
DesignWare you currently own. I was also told that each DesignWare is
equal to one SmartModel Premium, but I was not told how each SmartModel
would convert to DesignWare.
With that knowledge in hand, I decided to run a simulation experiment with
4 users using SmartModels on LMG's latest release. Here is what I saw:
4 users NC VHDL
4 users SmartModels
4 users Designware
0 users of FPGA Compiler or DC
Hmm, what is going on here? By this logic, I am limited to the minimum of
Smartmodels and Designware in simulation, not a sum. Yikes!!! I also
verified that SmartModels do not equate to DesignWares. I instantiated a
DesignWare UART and ran FPGA Compiler 3.5.1:
1 user FPGA Compiler
1 user DesignWare
0 user SmartModels
Hmmm, so that means my SmartModels do not convert to DesignWare using the
Synopsys license minimization technique as in simulation.
Unfortunately, this is the type of product rebundling I would expect from the
Borg, woops I meant Synopsys. Does anyone have the real deal on what is
happening to SmartModels and DesignWare?
Resistance is futile!

Hi, John,
As I said we were going to do, we updated our licenses using new Synopsys
"Increment" scheme, and combined our "Smartmodel" Synopsys LMG licenses
with our "DesignWare" license into one file. Easier to admin that way.
Then we hit the road block. Since these are "Increment" keys, there is no
implied order in which they are taken in the license file. Thus it is first
come, first serve. So, people requesting Smartmodel license to do board
level simulation sometimes grab DesignWare licenses instead of Smartmodel
ones.
This leaves people running older versions of Synopsys (specifically 99.10.4
which is the only one our ASIC vendor will sign off on) out in the cold
because these versions can't grab an available "Smartmodel" license and use
it as a "Designware". All you can do is get the person doing board level
simulation to get out of the simulator (if you can locate him) then hope
nobody else grabs the license before you get to the point in your Synopsys
compile where you need a DesignWare seat.
