WebMar 14, 2024 · Somewhere in your code you have a call to double() or single() . That is not permitted in code that is going to be used for HDL, because HDL seldom has floating point cores (floating point takes large die areas.) WebFor models referenced in accelerator mode, Simulink ignores the Wrap on overflow parameter setting if you set it to a value other than None. You can use the Model Advisor to identify referenced models for which Simulink changes configuration parameter settings during accelerated simulation.

Webfixpt_look1_func_approx('funcstr',xmin,xmax,xdt,xscale,ydt,yscale,rndmeth,errmax) optimizes the breakpoints of a lookup table over a specified range. The lookup table satisfies the maximum acceptable error, maximum number of points, and spacing requirements given by the optional parameters. Webnum2fixpt casts a real-world value represented in floating-point doubles, OrigValue, as a fixed-point number, outValue. Identifies the real-world value to be cast to fixed-point. Designates the desired fixed-point data type of outValue. Indicates the scaling of the output in either Slope or [Slope Bias] format.
