Dynamically Adding Voltage/Current Plots
It is possible to dynamically add .PLOT or .PROBE commands while a “batch” simulation is
running (not interactive mode). This could be useful if a simulation takes days to run, and you
realize when analyzing waveforms during the simulation that you need additional waveforms to
be plotted. It is also possible to send these commands to simulations running on remote
machines—simulations submitted to external dispatchers.
The steps required to use the simulation manager functionality are as follows:
Procedure
1. Run a simulation with Eldo.
By default, Eldo opens a communication port on the host it is running after a delay and
not before the elaboration of the design is finished. The default delay value is set to 30s.
This value can be modified with:
.option CONNECT_DELAY=
Once the port is opened the simulator creates an empty file in directory $HOME/.eldo/.
This file is named after the host IP address and port number, for example:
185.909.693.175:76. This file is removed once the simulator exits.
Note
To avoid the cost of port listening and file creation the simulation manager
mechanism can be completely disabled with the Eldo command line argument -
noconnect.
2. Run the simulation manager with eldo -connect.
To begin an interactive exchange, run the simulation session manager by entering on the
local machine:
eldo -connect
Eldo will browse the directory $HOME/.eldo/ in search of running simulations. The
active simulations are listed with their command line. A prompt is displayed enabling
you to interact with the remote simulations with the available commands.
3. Connect to a simulation.
Use the connect command to open a communication channel with a simulation. When
successful, the Simulation Connection Manager displays:
