I have not yet used the Simulation Builder in SPSS, but it should get you started.

A great deal of simulation can be done using INPUT PROGRAM and the many rv.* functions.

Check the archives of this list looking for "INPUT PROGRAM" and "RV."

There has also been syntax posted to generate variables from a given pop correlation matrix.  You should be able to adapt that syntax to create covariances.

Dear SEM experts,

We want to generate thousands of datasets with varied sample sizes (50, 200, 500) from a structural equation model (say, model with one endogenous latent variable and two exogenous latent variables, multivariate normal and skewed variables, each latent variable with three items that used 7-point ordinal options).  

We will use the data sets for our simulation studies.  Can you please suggest a software that can generate such data sets?
