Dear,
I want to know that whether I can reconfigure the integrated components(resistor, capacitor, etc.) to make desired analog circuit in GreenPAK or not.
I'm using the model SLG46517M, and I want to replace the discrete components with a one simple chip(GreenPAK).
Is it possible?
还有一个问题，有没有办法用verilog或其他模拟工具来综合编程的GreenPAK？
I want to simulate the whole system which is composed of my external circuit and GreenPAK chip.
Thank you,
Best regards

Dear Yuseungho,
谢谢你的提问，
1. Regarding the analog circuit you want to implement with GreenPAK, replacing the analog circuit depands on functionality and comlexity of this circuit. Could you show me your schematic and I will tell you if it is possible to integrate in GPAK. You need to know, that all outputs, except P-FET dedicated outputs, are digital (either Push Pull or NMOS Open Drain), so it would be hard to create true analog schematic. Please use my mailOleh.Sapiha@diasemi.com如果不't want to show your schematic on this forum.
2大多数GreenPAK IC都支持自己的模拟工具，但不幸的是，它不适用于SLG46517M。我们的工程师正在为这种特殊的集成电路进行模拟。没有从GreenPAK到verilog或其他模拟工具的各种转换器。因此，如果你想与外部公司一起模拟GreenPAK，你必须自己创建它，我会在这个过程中支持你。
Best regards.

Thank you for your help.
1这是一个非常简单的电路，只有三个电阻，一个电容，一个电感。只是前端部分，其他部分我自己做。
I fully understand that to make right judgment whether it is possible or not, I should show you the schematic.
In case you need, I will sent the schmetic by email. But it's a really simple circuit, so I just want to know how I can reconfigure the circuit if it's possible.
2. You said that the simulation is not available on SLG46517M, then how can I test the chip before programming?
I think the chip is quite simlar to the model SLG46537M, and I had checked SLG46537M simulation is available (right?).
If I design a circuit with SLG46537M, simulate it, and make the same design with SLG46517M, will SLG46517M model work as the same as designed SLG46537M? (I think it will work, but I want to make it sure.)
Thanks a lot

Yuseungho,
1. GreenPAK has only Pull Up/Pull Down resistors on PINs, no other resistors are aviable for progarmming. GPAK also doesn't have internal capacitor to program. But if you want, let's say, to recreate RC circuit in GPAK you can use Rising, Falling or Both edge delay, which is very similar to RC circuit. Basically GPAK is perfect to built it on logical components, since it has a bunch of LUTs (using which you create standard or custom logic gates), DFFs, Latches, etc.
2. If you have SLG46517M and Advanced DevBoard you can easily test your program using the Emulation Tools. In Emulation Mode chip will not be programmed, but you can test your design with the hardware. Please see the attachment
And, yes, you can Simulate the SLG46537 to check your design, since these ICs are very similar.

Thank you for your answer!
It's very helpful to me. Futhermore, I don't understand the way of recreating RC circuit with rising, falling, edge delay.
If you don't mind, would you show me the example of the circuit you mentioned?
Thank you very much.
Yuseungho,
Thank for your feedback,
When you apply some voltage on RC circuits you must wait some time until the voltage appears on the output and you need to wait some time after the input voltage goes low, until the RC circuit output goes LOW. This time is condisidered to be equal R*C. This coresponds the voltage level of ~0.7*Volltage_input. So using both edge delay in GPAK you can create the same time delay which would accord to time constant R*C. Please see the attachemnent.
