I was recently working on a mixed-singal simulation with AMS. To speed up the simulation, in ADE, I chose simulation performance mode as "APS", and manually chose 8 threads. In ADE, everything goes well, 8 cpu cores were brought up for the simulation, the simulation finished quite soon.
Then I generated an ocean script from ADE, and tried to run the script in OCEAN enviorment. But this time, it seems only one cpu cores was working and thus a very long simulation time was experienced. I checked there are the following warnings:
I use Cadence ic6.1.5-64b.500.16.2; MMSIM 121
the machine I used has 8 cores.
The automatic generated ocean script was as following (simplified) :
simulator( 'ams )
solver( 'Spectre )
resultsDir( "..." )
globalSignal(?name "gnd!" ?lang "CDBA" ?wireType "wire" ?discipline "" ?ground "YES")
globalSignal(?name "vdd!" ?lang "CDBA" ?wireType "wire" ?discipline "" ?ground "NO")
analysis('tran ?stop "30n" )
desVar( "vdd" 1.5 )
option( ?categ 'amsTurboOpts
temp( 27 )
Thanks in advance for your help!
In reply to alleyor:
It worked for me in IC615 ISR17 (so one after you) and in IC616 (uniMode is "APS"). Are you saying that it worked OK once you'd set uniMode to "APS" rather than the obsolete "Turbo" option? Turbo will (I think, from memory) nowadays set it to single threaded APS to provide some level of compatibility.
