.hex or .svf file from Mediatronix picoBlaze IDE

Hi, 

I am using Mediatronix picoBlaze to write assembly code 
for Xilinx picoBlaze and like to generate .hex 
or .svf file so that the code can be downloaded to 
the program rom via jtag port without re-synthesis. 

Could anyone advice me how to generate this type of file?
Thank you in advance.
