When I select Generate in StellarIP, with one of the 4DSP examples, 504_vc707_fmc142.dsn, I obtain the error "An error was detected while parsing the Netlist". As far as I understand, if this error were due to the ISE or Vivado source path, the library used or a licence problem, the error prompted would indicate it. I do not guess how is this error supposed to be approached, since no junction or wormhole is pointed in the Schematic. In any case, it is an example project, so there should not be netlist errors.
How do I correct this error?
It was indeed an error related with the Vivado source path and the licence. If any other person has this problem, make shure that both the Vivado source path and the licence are set properly.
