Handling Matrix-Like Circuits
To activate dedicated Eldo Premier algorithms performing matrix processing for the simulation
of “matrix-like” circuits, specify .OPTION PREMIER_MATRIX. This is specifically adapted
to the simulation of circuits with a regular structure such as an array of pixels and with highly
connected power grids. Due to their particular matrix structure, display panel circuits (TFT,
OLED) belong to this category of circuits. This option is of no interest to regular circuits
without dense power networks.
This option removes the bottlenecks associated with parsing, elaboration, partitioning, solver
generation, and simulation. The simulation solution is fast, accurate, and handles all the
physical effects described in the circuit, for example: coupling between rows and columns, IR
drop due to ground and power networks, row and column access resistors. This option is useful
for matrix-like circuits that cannot be handled by Eldo Classic; using this option consumes less
memory.
If this option is specified and the circuit is considered matrix-like, matrix processing is enabled,
and the following note is displayed:
Matrix processing is on.
If this option is specified but the circuit is not matrix-like, Eldo Premier disables the matrix
processing and displays the following note:
Matrix option was set by user, but matrix processing has been disabled by
the simulator.
Tip
See also “Eldo Premier Options” in the Eldo Reference Manual.
Limitations
• Only display circuits (TFT, OLED) are handled.
• The total power dissipation at DC is not computed (0 W is displayed).
• If many waveforms are generated, it may be useful to increase the heap size for EZwave,
see “Troubleshooting Memory Issues” in the EZwave User’s and Reference Manual.
