Simulation of Cordic sincos IP core: Wrong signals for negative input signals

Hi, i have problems with the Cordic sincos IPcore (https://www.altera.com/en_US/pdfs/literature/ug/ug_cordic.pdf). When i do the simulation, for positive signals i get the right signals but f...

I just read through the core description (https://www.altera.com/en_us/pdfs/literature/ug/ug_cordic.pdf). I can't figure out why you'd ever create a cordic (http://zipcpu.com/dsp/2017/08/30/cordic.html) that would use radians for its angles, given the serious problems with radian units discussed here.http://zipcpu.com/dsp/2017/06/15/no-pi-for-you.html (http://zipcpu.com/dsp/2017/06/15/no-pi-for-you.html)

Does this core really use radians?
