Resource Utilization and Performance
The ALTUFM IP core is only available for MAX II and MAX V devices. Resource usage is reported with
different interface options. Configuration mode settings described in the following tables are available in
the parameter editor.
Table 1: ALTUFM_SPI Resource Usage
UFM Blocks Logic Element Configuration Mode
(3)
Optimization (2) Access Mode (1)
1 147 Base mode Balanced Read/write
1 72 Base mode Balanced Read only
1 134 Extended mode Balanced Read/write
1 40 Extended mode Balanced Read only
Notes to Table 1–1:
1. Choose the access mode option to configure the UFM to the required mode of operation. Choose a design
implementation that balances high performance with minimal logic usage. The balanced optimization
logic option is set in Analysis and Synthesis settings (Assignments menu).
2. Choose the configure mode to set the mode of access with SPI interface to the UFM block. Set this option
to Base Mode or Extended Mode depending on the widths of the address and data buses.
Table 2: ALTUFM_PARALLEL Resource Usage
UFM Blocks Logic Element Data Width Address Width Optimization (2) Access Mode (1)
1 88 16 9 Balanced Read/write
1 69 16 9 Balanced Read only
Notes to Table 1–2:
1. Choose the access mode option to configure the UFM to the required mode of operation.
2. Choose a design implementation that balances high performance with minimal logic usage. The balanced
optimization logic option is set in Analysis and Synthesis settings (Assignments menu).
