问答对人有帮助，内容完整，我也想知道答案 0 刚入门不久，用的是Vivado2014.4 做一个工程的时候，仿真和综合都通过了，但是貌似是布线失败了，错误如下 [Place 30-640] Place Check : This design requires more RAMB36/FIFO cells than are available in the target device. This design requires 469 of such cell types but only 135 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. [Place 30-640] Place Check : This design requires more RAMB36E1 cells than 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. [Place 30-640] Place Check : This design requires more RAMB18 and RAMB36/FIFO cells than are available in the target device.
