Error with dbl data in FPGA

[cristina.lopez]

Hello,

I have a .vi inside a fpga. This .vi has a dbl data tipe inputs, and I can't run the vi because according to the list of errors:  type not supported in current tarjet.

I have a single board RIO (NI-sbRIO-9651-01c18bd6)  

Does anyone know what is the problem or a possible solution?

Thanks.

Attached capture of my errors list

You cannot use DBLs on an FPGA.  Change it to a SGL.

[Terry_ALE · Accepted solution]

DBLs are not supported on LabVIEW FPGA. Only SGLs and only after a certain version.

Muchas gracias 🙂

Another question, the fpga can't use the Quotient & Remainder that's right? , how can i do the same operation without Quotient & Remainder

What are you trying to do with the Q&R?  I thought it was available in FPGA, but it is expensive (lots of fabric and multiple clock cycles to complete).

[cristina.lopez]

I need to know the remainder and quotient of the division of two variables.

The fuction is in palette but when i put this in block diagram, the error list say me that this fuction is not supported

[cristina.lopez]

I want to do this

[Terry_ALE]

Quotient-Remainder is not supported in a Single Cycle Timed Loop.

You could do a repeated subtract. It will take multiple cycles but this is how certain functions are on the FPGA. What is the cycle time?
