how to use tabletop simulator for prototyping

įirst things first, of course - this is a $20 program you’ll need to buy (though it does go on a sale. It will be edited, updated, and sections might move or be deleted to make it easier to follow. There is a learning curve, but by the time you’ve reached the end of this piece, you will have created your own game (or big parts of it!) in the program.Ī quick note: this is a living blog post. It came out in 2015 following a successful Kickstarter, and has become the most popular way to play games virtually. Because Simulink and PSIM can have different time steps, it is not a good idea to exchange data if the data are of logic signal type (0 and 1).Tabletop Simulator is a powerful ‘sandbox’ program that makes it surprisingly easy to show off your game in a virtual space. Simulink must be set up to have the Solver Type as Fixed-step with the time step the same or close to the PSIM time step, or if the Solver Type is Variable-step, a zero-order-hold must be used with the sample time the same or close to the PSIM time step. Certain restriction is imposed on the selection of the solver type and the time step in Simulink when performing the PSIM-Matlab/Simulink co-simulation. The memory block introduces one integration time step delay. To break an algebraic loop, place a memory block at each output of the SimCoupler model block. Some versions of Matlab/Simulink can not solve a system containing algebraic loops, while others can solve the system but with degraded performance. Additional remarks : When the SimCoupler model block is used in a feedback system in Simulink, the SimCoupler model block may be part of an algebraic loop. The setup of the co-simulation is now complete. In this case, we used a variable step with a zero-order-hold set to 2us (see additional remarks next page).ĩ /8 16. Set the step size to be the same as or close to PSIM s time step. Under Solver Options, set the Type to Fixed-step. Finish the connection for the Simulink part : go to the Simulation menu and select Simulation Parameters.

Current 1 input 2 outputs Voltage If the number of link nodes in the netlist is changed later, go to the Edit menu in Simulink and choose Update Diagram.

In this example we have from the top to the bottom the Current and the Voltage. The order of the output ports had been decided at step 7. In this case, there will be 1 input port and 2 output ports (except if you have the demo version and if you did not add the second OUT SLINK). 8 /8 If you have more than one IN and OUT SLINK, the number of input and output ports for the SimCoupler model block will automatically match those defined in the PSIM netlist.
