使用Xilinx公司的Vivado进行DDR4 IP配置时，可能会遇到DDR4 IP中的默认配置中没有所需内存条型号的情况。
解决方案：下载所用内存条的对应手册与Xilinx AR#63462页面上.csv文件进行DDR4内存条的客制化配置。 remove duplicate contacts from vcf files
因Xilinx DDR4 IP配置参数契合镁光内存条的Datasheet，所以推荐使用镁光内存条来进行DDR4 IP核配置。 import vobject def remove_duplicates(input_file
import vobject def remove_duplicates(input_file, output_file): seen = set() unique_contacts = []
with open(input_file, 'r') as f: vcards = f.read().split('END:VCARD') for vcard in vcards: if 'BEGIN:VCARD' not in vcard: continue vcard = vcard + 'END:VCARD' # Use FN (Full Name) as unique key – adjust as needed try: obj = vobject.readOne(vcard) fn = obj.fn.value if hasattr(obj, 'fn') else '' if fn not in seen: seen.add(fn) unique_contacts.append(vcard) except: continue # skip malformed vcards
