hi all.......... 

 

i had one doubt............. 

 

i use an EP3C120F780 FPGA and it has 3,981,312 memory bits....however i cant use more than 73% of this........... (not compile project with more than 3,000,000 memory bits....) 

 

 

why this occurs? .... can i improve this performance???? how can i reduce these bits...... 

 

i need port my projecto to EP4C75 and this had only 2,810,880 memory bits and i need improve this...... 

 

 

thank you for replys

Hi. 

Your design uses more memory blocks (M9K, MRAM, etc.) than there are in the device. You can try to optimize block usage by sharing address and write enable lines of different memory instantiations.
