请问在capture CIS中能否给器件挂载IBIS模型?
我的意思,存在IBIS模型库,在设计原理图时,器件的property中就加载IBIS库,然后在PCB SI中仿真和抽取拓扑时,就省去给器件赋予model的步骤。
不能的,否则我们就省事了呵呵
不能的吧!
确认?
听说是可以的,我自己也查了元件的属性,里面有 signal Model 属性,但我没有尝试成功
能截图指出你说的signal model在哪儿么?
进入capture---双击元件进入 Property Editor----filter中选择 cadence Allegro
就会看到signal model

cadence用的是dml,你直接挂个ibis上去,肯定不能直接仿真。
maybe那边只是作为一项attribute吧,没见到调用路径啊。
小编,我在使用了dml文件不成功后,才尝试ibs文件的。
共尝试了赋值
E:\cadencework\SIsimulation\k4s56xx32h.dml
k4s56xx32h.dml
E:\cadencework\SIsimulation\k4s56xx32h.ibs
k4s56xx32h.ibs 和
K4S561632H_T75 (器件具体型号)
都没成功。
当然自己可以建一个.dat文件,在关联模型时load这个文件,批量关联模型
如
AT91RM9200PQFP208_PQFP208_AT91R AT91RM9200PQFP208 at91rm9200
K4S561632H-UP75_TSOP54II_K4S561 K4S561632H-UP75 K4S561632H_T75
看到了,我估计这个要自己做库才能调用,而且不知道导入PCB是否能一起带进去
你说的文件应该就类似hyperlynx中的.ref IC automapping file,批量关联模型。但SQ中具体如何操作没研究过,我还是用土办法,一个个的添加model
能给出Hyperlynx的ref IC automapping file的操作说明吗?
这个文件是在做库时就将模型关联上,后面自动生成这个文件,还是做设计时手动创建的?
“能给出Hyperlynx的ref IC automapping file的操作说明吗?”
hyperlynx的.ref文件是完全基于软件工具本身实现的。你研究这个等于说实在研究应用软件本身了。
需要手动创建.ref文件

问题已经找到答案了,并且尝试成功,方法如下
How can I add the SIGNAL_MODEL property to the Capture CIS parts for transfer to Allegro SPECCTRAQuest?
You need to add the SIGNAL_MODEL property to the Capture CIS part and then add the SIGNAL_MODEL=YES entry under the [ComponentInstanceProps] section in the allegro.cfg file.
To add the SIGNAL_Model property to a Capture CIS part:
- Select the part in Capture CIS and choose Edit > Properties. The Property Editor window appears.
- From the Filter by drop-down list box, choose Cadence-Allegro/SPECCTRAQuest/APD to make the SIGNAL_MODEL property visible, if it already exists.
- If the property does not exist, add the property by either clicking New Row or New Column and then entering SIGNAL_MODEL in the Name text box of the Add New Row/Column dialog box and the signal model name in the Value text box.
- Click OK and close the Property Editor window.
- In the Project Manager, highlight the design file.
- Choose Tools > Create Netlist. The Create Netlist dialog box appears.
- Click the Allegro tab, if not selected already.
- Click Setup. The Setup dialog box appears displaying the path where the configuration file (allegro.cfg) is located in your computer.
- Click Edit. The allegro.cfg file opens in a text editor.
- Add SIGNAL_MODEL=YES under the [ComponentInstanceProps] section as shown below[ComponentInstanceProps]
GROUP=YES
ROOM=YES
VOLTAGE=YES
SIGNAL_MODEL=YES - Click OK in the Setup dialog box.
- Click OK in the Create Netlist dialog box to generate the transfer files for Allegro
