I was comparing implementation on virtex 6 (ml605) and zynq (zc702) of my hardware design composed of a customized IP and microblaze/ARM-9. The problem is that on the virtex 6 xps tells me that the design is too large to fit the device (RAM are overused 194% while 71% of slice LUT are used and only 1 % of DSP)
I was convinced that the programmable logic of the virtex 6 is bigger than the zynq so I am wondering if I missed something in my virtex design or if there is a way to intervene in order to map the design.
I would be very grateful if someone helps !

So one design (Virtex) has a Microblaze core, while the other design (Zynq) uses the Zynq's built-in ARM processor? It sounds like that's the explanation for the difference in resources. Is the Microblaze using a vast amount of block RAM for its own storage?

as @u4223374 says, check the number/size of BRAMs MB subsystem is using. You can get a hierarchical area report and see where the design resources are going.
