Supported Models
Eldo Premier supports the following models:
• All SPICE basic models (R, C, L, E, F, G, F, and so on).
• Eldo models (UDM and GUDM; charge controlled models only).
• Verilog-A (default flow only).
• VHDL models (when used inside Questa ADMS).
• Capacitive MOSFET models.
• A subset of Eldo built-in macromodels: all in the analog, digital, and mixed-signal
groups; Switch (Sxx) from the switched capacitor group.
Limitation: Eldo Premier does not plot the nodal current of macromodels, for example
I(Ymacro.2).
• Eldo S-domain (FNS) and Z-domain (FNZ) filters.
• S Parameters FBLOCK (block defined with frequency tabulated data in Touchstone
format).
• LDTL, W and U models (transmission line models).
• Ideal transmission line model (T element).
• Microstrip models.
• R, L, C elements defined with an expression (VALUE=) containing the FREQ
keyword.
• E and G of FREQ type (frequency dependent voltage-controlled voltage sources and
voltage-controlled current sources).
Other Supported Functionality
Eldo Premier supports the following, with some exceptions:
• All features of ECL except Simulation Dynamic Control, see “Eldo Control Language”
on page 801.
• Transient noise analysis subset, see “Transient Noise Analysis in Eldo Premier” on
page 90.
