【FPGA_012】布线报错ram不够

[Place 30-640] Place Check : This design requires more RAMB36/FIFO cells than are available in the target device. This design requires 145 of such cell types but only 140 compatible sites are available in the target device. Please analyze your synthesis results and constraints to ensure the design is mapped to Xilinx primitives as expected. If so, please consider targeting a larger device.
