I use the Ramp up and the Polar (phase and amplitude) to generate the one cycle sin.

the register is :

   parameter Data0=32'hE000_0002;//for address 0x00;

  parameter  Data1=32'h150F4114;//for address 0x02;

  parameter  Data2=64'h080f_ff0F_C000_0001;//for address 0x0e

//tthe  ram data is :

 

RAMbit<={ //25*32
32'h0000ffff,32'h0a3dffff,32'h147affff,32'h1eb7ffff,32'h28f4ffff,

32'h0000ffff,32'h0000ffff,32'h0000ffff,32'h0000ffff,32'h0000ffff,

32'h0000ffff,32'h0000ffff,32'h0000ffff,32'h0000ffff,32'h0000ffff,

32'h0000ffff,32'h0000ffff,32'h0000ffff,32'h0000ffff
};

I read the register the data is corret. but the out wave isn't my need.I donn't  know how to ready the data for the   Polar (phase and amplitude),who can tell me or give me one example for the polar,thanks!
