Quartus II中的浮点数

I am designing a FIR filter in Verilog with Quartus II. I need floats for my coefficients so I tried using float however reall is not supported by Quartus so what do I do?

我正在使用Quartus II在Verilog中设计一个FIR滤波器。我需要浮点数用于我的系数所以我尝试使用float但是Quartus不支持reall所以我该怎么办?

Thanks

You can't use real, since it is not synthesizeable, follow IEEE-754 format for floating point. can be done by using structural modelling with Altera Megafunctions.

你不能使用real,因为它不可合成,遵循IEEE-754格式的浮点。可以通过使用Altera Megafunctions的结构建模来完成。

Its recommended to use MAC unit, with floating point options.

建议使用MAC单元,具有浮点选项。
