fiveight posted a comment on discussion ngspice-users
I get it. Thank you!

I have fixed this. I built the executable file from source by myself. And I changed SIMinfo's simulator name. So I meet this problem. After I change SIMinfo's simulator name to its origin string, I fix this. But I can't understand, why this problem has to do with SIMinfo's simulator name. I think Cir file parse process should not couple with simulator name. Thanks!

Hi All!

The return value of quit command is 1 wether use 26 or 27. But 26 will clear the memory, and 27 will not. My Windows app is build by VS2008, runs on Windows 7 32bit. Thanks!

Thanks! I am using ngspice as shared library. So I decide to save the vactor values that from callback function in memory, and output a VCD file myself. Then let gtkwave use the VCD file.
-
Hi All: I know that ngspice can save event driven nodes to vcd file, and view the vcd file with gtkwave. But I am interesting in analog circuit now, and can not find a way to output analog results to vcd file. How to save analog results from ngspice and view them in gtkwave? Thanks!
-
Thanks! It works good now. I find a new problem in shared-xspice+3, and it does not exist in release version of 27. If the include statement in cir file have same line, the source command will return 1. I give an example in attached file. Put the cpu folder in D:.

Thanks! I have tested shared-xspice+3 branch with my app on Windows 7 32bit. There is no memory leaks any more. But I find a very odd problem, that d_jkff model can not use a model name with number prefix. The release version of ngspice 27 can use number prefix model name. I give a cir below with d_jkff model name have number prefix, during simultion, the two output pins of jkff are all 0. If change the model name from "74JK_FLOP" to "JK_FLOP", it works good, the two output pins value is 0 and 1....

Thanks! You mean I can still use ngGet_Vec_Info function to get digital node values in my app? I find that I get digital node values of v_realdata usually is 0.0000 or 1.0000 with this function in 27 or 26. But with shared-xspice+2, I get values is -2.6569842580370804e+303 or 9.0737898161532819e-308.

OK, This is my sample code, just call get_vec_info function several times in senddata callback funtion make 27 leak memory. The input command is: source mem.cir bg_run quit Begin memory is 1.6MB Befor quit command is 142.9MB After quit command is 138MB I build ngspice.dll and six cm files on Windows 10 64bit with vs2017, the solution config is Release OpenMP, and the plateform is X86. Thanks!
-
OK, Thanks! I need a few days to make a sample of my code.
-
Thanks! I have tested your code with 26 and 27, all of them can release memory after quit command. Then I compare your code and my code, and I find the problem. In my code, every time when SendData callback function was called, I call ngGet_Vec_Info function many times to get a lot of node values by node names in SendData callback function. If I delete these code in SendData callback function, 26 and 27 can work good with my app. I think maybe there is some problem with ngGet_Vec_Info API function...

Thanks! But I almost tried every possible position to call FreeLibrary function, 27 still can not release memory(even after I have my lunch and return to my desk ), but 26 can. I think the posting message is safe. Because the main thread of my Windows app has a message loop. Sending quit command and unload DLL file are all in this loop, they must be sequencial. Maybe the memory managment in 27 has something wrong.

I find that these .save commands have nothing to do with the digital circuit simulation, but the return value is 0 indeed ! If I send save commands without dot, the simulation immediatly stop after bg_run command. So I delete all these useless save commands now. My app runs on Windows 7 32bit, and I don't have 64bit version of my app. So please check ngspice.dll-27 32bit version. And teach me how to send quit command correctlly. Thanks!

OK, I find a problem that when I send 'quit' command by ngSpice_Command function, the return value is 1. Both 26 and 27 have this problem. But 26 will release memory normally, and 27 will not. Where should I send th 'quit' command? I have tried to send it in the ControlledExit callback function or the message response function of my app, all of them make my app crash.

Hi All: I find that NgSpice-27 DLL can not start simulate on Windows XP. Is this a feature? Thanks!
-
Hi Holger! Does Ngspice-27 DLL support "save none" command now? And is this available for XSPICE event nodes? Thanks!
-
Maybe it is too hard. I want to accomplish some features like Proteus. For example, simulate MCU and peripheral equipment chips, and let them work together. Make the designer of schematic can read register values of these chips at any time or every clock when simulating. Maybe I should use code model of XSPICE to accomplish this.
-
Thanks! I have the same idea before I create this topic. But I am not sure.Now I will try this. If it works, does this mean I can implement any chips in this way? Maybe I can program 8051 8086 8253 8259 ......chips, and these chips can simulate with ngspice.

Thanks! But I didn't understand. Do you mean writing my own code model?

Hi All: I am using ngspice.dll. I want to set memory data of device that used d_ram model befor starting simulation like ROM, and access memory data of this device every time when send data callback function was called. For example, get the value of one byte with a given address, or set the value of one byte. How can I make this? Thanks!

Thanks. I have test, that ngspice is case insensitive when load spice file, so I send alter command in lower case. It is ok.
-
Hi All: I send alter command to ngspice.dll like this: alter @v.xH.v2 = 2 When I user upper case after "@v.x", it failed. But lower case and number is ok. So is ngspice not case sensitive? If then I will change all device name and net name to lower case.

So a tri-state buffer is not of interest if used a a single device, but only when you connect the outputs of several tri-states together. I See. Thank you very much!

Thank you very mush! But as the first post of this thread said, I am using DLL, and you told me the reason at the second post. With my app and ngspice.dll, I get value from output pin always as same as input pin, It has nothing to do with enable pin is 0 or 1. So I can not use this d_tristate model.

Thank you very mush! But as the first post of this thread said, I am using DLL, and you told me the reason at the second post. With my app and ngspice.dll, I get value from output pin always as same as input pin, It has nothing to do with enable pin is 0 or 1.

Is there any way I can find that weither Tri-state Gate output is 1 or 0 or high impedance?
-
why not

Thanks!

Hi All: I am working in interactive mode, and doing transient analysis on digital circuit. I can get nodes value in send data callback funtion by call ngGet_Vec_Info function with nodes name, but these values use double type. I notice the section 12.5 in manual, but how can I use digital node type? and get nodes value like 0s 1s Us... in send data callback funtion. Thanks!

Thank! But I still think while simulation ngspice does not need all history values of nodes. Hope ngspice can supply a command to clear these useless values next version.

I am working in interactive mode, and doing transient analysis on digital circuit. Is there any way to make ngspice to delete history nodes value during simultion? I think while simulating ngspice dose not need all history nodes value. I use Multisim to simulate my circuit too. It can use static memory while simulating, if I set logic analysis instrument in circuit, Multisim eat memory slowly.

Hi All: I am working with ngspice.dll. And I get nodes value in senddata callback function. I want to store nodes value of current moment only by myself, and make ngspice not to store history nodes values. So ngspice will not eat memory more and more. How can I do this? Thanks!

Thank you very much! But I notice that the command function still use ascii string argument like / Caller may send ngspice commands to ngspice.dll. Commands are executed immediately / IMPEXP int ngSpice_Command(char* command); How can I send unicode command string to this function?

Hi All: I use command "source" to send a .cir file to ngspice. If this file path include space and Chinese characters. The command failed. How can I resolve this problem? Thanks!
