reagarding simulation error

hi all...
when i'm simulating the circuit...i'm getting o errors and 0 warnings...
but i'm getting simulation error...
errors are:
------ Checking SPICE netlist for 555timercktthreephasefullwavenew - 2009-10-15 17:16:06 ------
======= SPICE Netlist check completed, 0 error(s), 0 warning(s) =======
Error Message From Simulation: doAnalyses: Timestep too small
Error Message From Simulation: tran simulation(s) aborted


i'm changing time step in simulate-->interactive simulation settings-->maximum time step
i'm changing that max time step....but i'm getting the same error...
timestep is small...
how to overcome this problem.......

Hi,

 

Please have a look at the Time Step too Small knowledge base and go try some of the recommendations, it may or may not fix the problem.  Post the Multisim file here if you can, but if the design is confidential, you can send us the file by create a service request at ni.com/ask.
