allegro导入网表错误详解4页

1、此文章由资深Layout攻城狗LGW（Gavin）提供，是其的经验笔记，可转可拷。错误种类1：#1 WARNING(SPMHNI-192): Device/Symbol check warning detected.WARNING(SPMHNI-194): Symbol SOD_123 for device SCHOTTKY_SOD_123_B5819W(DNI) not found in PSMPATH or must be dbdoctored.此类错误和没有PCB封装有关。错误种类2：ERROR(SPMHNI-196): Symbol UTH12T02 for device XFMR-H

2、1102_0_UTH12T02_H12T02 has extra pin 14.此类错误表示原理图符号的PIN脚和PCB封装PIN数量或命名不对。错误种类3：#5 ERROR(SPMHNI-176): Device library error detected.ERROR(SPMHNI-190): Device problem FERRITE BEAD_0_LC0805_100MHZ;10. Package property error: VALUE=100Mhz;100ohm25%_3A. Illegal character(s) present in the name or value.E

3、RROR(SPMHNI-170): Device FERRITE BEAD_0_LC0805_100MHZ;10 has library errors. Unable to transfer to Allegro.这个错误是因为原理图元件的VALUE有非法字符。经实验发是不能有“”这个符号错误种类4：#1 ERROR(SPMHNI-176): Device library error detected.ERROR(SPMHNI-200): Error with pin number Y25 in device AML8726-MX_0_BGA487_1840X1840_6: Unable to

4、 find pin name in adfncpin.此问题一直没找到真正的原因，这个错误是说元件name有问题，我每次编辑元件再把name改一下就可以了，但是没有找到规率和原因。错误种类5：ERROR(SPMHUT-1): Illegal character(s) present in the name or value.如要原理图用中文命名，将出现这种错误。错误种类6：#1 WARNING(SPMHNI-192): Device/Symbol check warning detected. helpWARNING(SPMHNI-194): Symbol CD43 for device IN

5、D_0_CD43_3.3UH not found in PSMPATH or must be dbdoctored. 表明找不到封装错误种类7：#1 ERROR(SPMHNI-191): Device/Symbol check error detected.ERROR(SPMHNI-195): Symbol QFN40P800X800_68 for device BCM43217TKMLG-W1000-20892_QFN40 is missing pin H. 表明PCB封装少H脚.错误种类8：WARNING(SPMHNI-337): Unable to load symbol SOT23 f

6、or device FET-MOS-P_6_SOT23_DISCRETE_TG21: WARNING(SPMHUT-127): Could not find padstack SMD20_17.#18 WARNING(SPMHNI-192): Device/Symbol check warning detected.这个错误提示找不到SMD20_17这个焊盘，我到自己的库里发sot23这个封装指定的焊盘是SMDR100X130的焊盘。最后发现是软件自带的库也有一个sot23的封装，而这个封装刚好指向SMD20_17这个焊盘，刚好焊盘的默认路径（$psmpath）被我删除了。最后把库路径的优先级

7、改了一下，把默认路$psmpath放最后。问题解决错误种类9：#1 WARNING(SPMHNI-303): PST file warning detected.WARNING(SPMHNI-311): Multiple instances of property NO found on net PCIE_TDP.这个警告不知道什么意思，要解决的话重新在原理图上连线就好了。不过可以不用管这个警告，对导网表没影响。错误种类10：RROR(SPMHNI-164): Problems with device R_RC080511111111111111111111111. JEDEC_TYPE pr

8、operty RC0805111111111111111111111111111111 is illegal: Package name is too long.这个警告是说封装名名字太长错误种类11：WARNING(SPMHNI-192): Device/Symbol check warning detected. helpWARNING(SPMHNI-337): Unable to load symbol SOP-8 for device 9346_6_SOP-8_PIC12F508/509: WARNING(SPMHUT-127): Could not find padstack SMD

9、08S18. help这个警告和错误种类8：很像,我查了一下,发现是库里面没有SMD08S18这个焊盘封装.错误种类12：#1 WARNING(SPMHNI-303): PST file warning detected.WARNING(SPMHNI-311): Multiple instances of property NO found on net USB_DP.这个警告是说原理图的USB_DP网络有多个属性定义。先在原理图中找到这个网络。解决方法有两个，1.重新连线。 2.双击这根连线，打开属性，把NET_PHYSICAL_TYPE 和NET_SPACING_TYPE两属性改成一样或把

10、NET_SPACING_TYPE这个属性全删了。说简单些就是在原理图中设了规则,但在PCB中又没有按这个规则来.如下图：错误种类13：#2 WARNING(SPMHNI-192): Device/Symbol check warning detected. helpWARNING(SPMHNI-337): Unable to load symbol R_EXB18V used by RefDes RN201 for device RN8D3-A_R_EXB18V_DISCRETE_10K(D: WARNING(SPMHUT-127): Could not find padstack SR030

11、X020. help此警告是说R_EXB18V 这个封装缺省SR030X020这个焊盘.错误种类14：Starting to read F:/MY JOB/KA3200 V1.0/intput/allegro/pstchip.dat #1 ERROR(1) Syntax error : unexpected character PIN_NUMBER Syntax error : Expected . range specifier at line 4565 File name : F:/MY JOB/KA3200 V1.0/intput/allegro/pstchip.dat这个错误是说原理图

12、的元件有非法字符.”. .” 原后要我们在原理图的”pstchip.dat”文件中找”4565”这一行,里面有详细说明.错误种类15：#1 ERROR(40) Object not found in database Pin number 3 not found in database In line 11026 (原理图11页，026不知是什么意思) File name : E:/File/Apollo Lake/input/allegro/pstxnet.dat Please save all files and contact Cadence这个错误是说原理图的11页有个器件的第3脚有问题。错误种类16:#1 ERROR(SPMHNI-176): Device library error detected.ERROR(SPMHUT-115): Pin ALWAYS ON CLK32KOUT1 for function RK808_7_LCC68_7X7_P3A5_0A15X0A8 on device RK808_7_LCC68_7X7_P3A5_0A15X0A8 has a swap/
