Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideAppendix A: Using LMTV with Synopsys Models// Such a model would typically have one window called UMEM.// This window is a 4K deep array of 8 bit registers. In// particular, the user is interested in these 3 locations:// Interrupt service routine, LOW ADDRESS: 100// Interrupt service routine, HIGH ADDRESS: 101// Control store : 200// that are significant to the design.reg [7:0] ISR_LOW; // variable to map to location 100reg [7:0] ISR_HIGH; // variable to map to location 101reg [7:0] CONTROL; // variable to map to location 200// enable monitoring of these variables$lm_monitor_vec_map( ISR_LOW, U1, "UMEM", 100 );$lm_monitor_vec_map( ISR_HIGH, U1, "UMEM", 101 );$lm_monitor_vec_map( CONTROL, U1, "UMEM", 200 );// ... at this time, you can read, write, or trace these// variables. For example, assign the address of the interrupt// service routine to be 0x5000ISR_LOW = 0x00 ;ISR_HIGH = 0x50 ;// or the same assignment can be done as follows:define ISR {ISR_HIGH,ISR_LOW}ISR = 16h5000 ;// this one statement will access two different// and independent memory locations at once.// later in the simulation, you can disable monitoring// for the ‘CONTROL' register:$lm_monitor_vec_unmap( CONTROL, U1 );// or you can disable monitoring of all windows in that instance:$lm_monitor_vec_unmap( U1 );October 6, 2003 Synopsys, Inc. 279
