Hi,
I use the night build of KiCAD 6 on Linux Mint 19.1.
I would need to set up directives in eeschmea what signals will be rendered and ideally perform some mathematical operations over them.
For example, I need to render a transmission that is in two blocks. I use these directives:
.ac dec 200 1 1Meg
.control
run
plot db(v(out)) - db(v(in))
.endc
Then I will generate net spice: Eeschema -> File -> Export -> Netlist
Then I run ngspice: $ ngspice my_netlist.cir
and get the following result.
Would a similar result be achieved with the built-in Spice Simulator? So that you don’t need to generate a build, but just run a simulation in Eeschema?
When doing this, the issue is I have to insert 0V V source to plot the current. I see KiCad try to add save statement to avoid doing this. But it is not a easy solution for doing with directive. Do you have other trick for this? So automatically save internal data of basic model like resistors, caps, inductors…?
I wish 5.x may have a faster hotkey to activate external ngspice or other simulator. This is the wish because I only have a limited knowledge from 4.1 version, and some 5.x versions. I think I have attempt to request from bug tracking, but seem like I’m not put it in the right way. And so they was mostly dismissed with comments.
[ADDED]
in 4.1x I have to do Alt+T, N, Ctrl+Tab (Three times), Alt+R.
But some case, after using hotkey for switching tools. The Alt key stop working like one of the report I did in the bug tracking for 5.x versions.
[ADDED2]
Also, since 5.x change directive way, and attempt to parse them - It for my use case, make it difficulty for:
Comment or uncomment directives - required to add “*” on every line in directive for 5.x vs. 4.1 only a first line in the directive. I use many directives for simulate difference type/situation.
Switching between 4.1 and 5.x for check features or make sure new version is mature enough for my team require change directive remove/add “+pspice” on every simulation project and directives!
Thank . I had done all of that. Just to hope some one have a second though about all of the dismissed request by put this in here. I have to spend some searching time to figure out which were those report links later.
