WebThe syn_ramstyle attribute supports the values of no_rw_check and rw_check. By default, the synthesis tool does not generate glue logic for read/write address collision. Use syn_ramstyle="rw_check" to insert glue logic for read write address collision. Use syn_ramstyle="no_rw_check" to prevent glue logic insertion. WebCollection of small but useful HDL cores.
